CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is related to U.S. patent application Ser. No. ______ [Attorney Docket No. 55956.176US02] filed Jan. 27, 2025 and entitled “SPOTTER ARM FOR WEIGHTLIFTING APPARATUS” which is hereby incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present invention relates generally to weightlifting apparatus, and, more particularly, to weightlifting apparatus which can be operated safely and conveniently.BACKGROUND
[0003] When lifting weights, for some lifts, an assistant or spotter may be used, for example, to help the weightlifter finish a lift in the response to the weightlifter failing to be able to do so. For example, during a bench press lift, after a number of successful repetitions, the weightlifter may no longer be able to complete a final repetition due to fatigue. In such circumstances, the spotter may apply an upward force to the weightlifting bar to assist in the completion of the final repetition.
[0004] Some weightlifting apparatus have spotter arms which can be used, for example, by a weightlifter after failing during a bench press lift. The spotter arms are arranged so that the weightlifter can lower the weightlifting bar to rest the weightlifting bar on the spotter arms.SUMMARY
[0005] One inventive aspect is a weightlifting apparatus including first and second support posts, and first and second spotter arms permanently connected to the first and second support posts, respectively, where the first and second spotter arms are configured to be selectively positioned along the first and second support posts to define an adjustable barbell boundary.
[0006] In some implementations, the first and second spotter arms extend continuously from the first and second support posts to define the barbell boundary.
[0007] In some implementations, the weightlifting apparatus also includes first and second stops connected to the first and second support posts, respectively, where the first and second stops are positioned to prevent the barbell boundary from being closer than a predetermined distance to one or more surfaces supporting the first and second support posts.
[0008] In some implementations, the first and second spotter arms are selectively slidably connected to the first and second support posts, respectively.
[0009] In some implementations, the first and second spotter arms are respectively positioned on the first and second support posts by first and second handle detents.
[0010] In some implementations, the first and second handle detents each have a handle adjacent a detent actuator.
[0011] In some implementations, the weightlifting apparatus also includes first and second barbell catches, where the first and second barbell catches are configured to hold a barbell.
[0012] In some implementations, the first and second barbell catches are slidably connected to the first and second support posts, respectively.
[0013] In some implementations, the weightlifting apparatus also includes a weightlifting bench, where the barbell boundary in defined in relation to a supporting surface of the weightlifting bench.
[0014] Another inventive aspect is a method of operating a weightlifting apparatus, the method including releasing the first spotter arm from a first fixed position on the first support post, releasing the second spotter arm from a second fixed position on the second support post, sliding the first spotter arm along the first support post to a third fixed position on the first support post, sliding the second spotter arm along the second support post to a fourth fixed position on the second support post, fixing the first spotter arm at the third fixed position on the first support post, and fixing the second spotter arm at the fourth fixed position on the second support post.
[0015] Another inventive aspect is a method of manufacturing a weightlifting apparatus, the method including attaching a first support post to a second support post, permanently attaching a first spotter arm to the first support post, where the first spotter arm is configured to be selectively positioned along the first support post, and permanently attaching a second spotter arm to the second support post, where the second spotter arms is configured to be selectively positioned along the second support post, where the first and second spotter arms define an adjustable barbell boundary.
[0016] In some implementations, the first and second spotter arms extend continuously from the first and second support posts to define the barbell boundary.
[0017] In some implementations, the method also includes forming first and second stops on the first and second support posts, respectively, where the first and second stops are positioned to prevent the barbell boundary from being closer than a predetermined distance to one or more surfaces supporting the first and second support posts.
[0018] In some implementations, the first and second spotter arms are selectively slidably connected to the first and second support posts, respectively.
[0019] In some implementations, the first and second spotter arms respectively include first and second handle detents, where the first and second spotter arms are respectively movable along the first and second support posts by the first and second handle detents, and where each of the first and second handle detents has a handle adjacent to a detent actuator.
[0020] In some implementations, the method also includes attaching first and second barbell catches to the first and second support posts, where the first and second barbell catches are configured to hold a barbell, and where the first and second barbell catches are slidably connected to the first and second support posts, respectively.
[0021] Another inventive aspect is a method of operating, the method including with first and second spotter arms of weightlifting apparatus permanently connected to first and second support posts of the weightlifting apparatus, defining an adjustable barbell boundary, maintaining a first permanent connection between the first spotter arm and the first support post while the first spotter arm is released from a first fixed position on the first support post, maintaining a second permanent connection between the second spotter arm and the second support post while the second spotter arm is released from a second fixed position on the second support post, maintaining the first permanent connection between the first spotter arm and the first support post while the first spotter arm is slid from the first fixed position to a third position, maintaining the second permanent connection between the second spotter arm and the second support post while the second spotter arm is slid from the second fixed position to a fourth position, and maintaining the first and second permanent connections while the first and second spotter arms are respectively fixed to the third and fourth positions.
[0022] In some implementations, the method also includes preventing the first and second spotter arms from additional sliding with first and second stops connected to the first and second support posts, respectively, where the first and second stops are positioned to prevent the barbell boundary from being closer than a predetermined distance to one or more surfaces supporting the first and second support posts.
[0023] In some implementations, the method also includes maintaining a third permanent connection between a first barbell catch and the first support post while the first barbell catch is released from a fifth fixed position on the first support post, maintaining a fourth permanent connection between a second barbell catch and the second support post while the second barbell catch is released from a sixth fixed position on the second support post, where the first and second barbell catches are configured to hold a barbell, maintaining the third permanent connection between the first barbell catch and the first support post while the first barbell catch is slid from the fifth fixed position to a seventh position, maintaining the fourth permanent connection between the second barbell catch and the second support post while the second barbell catch is slid from the sixth fixed position to an eighth position, and maintaining the third and fourth permanent connections while the first and second barbell catches are respectively fixed to the seventh and eighth positions.
[0024] In some implementations, the first and second spotter arms are respectively positioned on the first and second support posts by first and second handle detents, each having a handle adjacent to a detent actuator.
[0025] The scope of the invention is defined by the claims, which are incorporated into this section by reference.

[0036] Some embodiments include a weightlifting apparatus that has both spotter arms and J-hook barbell catches mounted permanently on the support posts. As a result, the safety spotter arms, and barbell catches are always present. Additionally, there is a minimum height that the spotter arms are allowed to be lowered to. The minimum height may be high enough to keep weightlifters safe in the event of muscular failure.
[0037] By keeping the spotter arms and barbell catches permanently on the support posts, the spotter arms and barbell catches are reliably available for weightlifters to use. This is particularly advantageous, for example, if the weightlifting apparatus is placed in a location used by many different weightlifters, such as a membership gym. In some embodiments, adjusting the spotter arms and barbell catches is advantageously intuitive. In some embodiments, the spotter arms and barbell catches are attached to the support posts by an attachment mechanism which allows for placement of the spotter arms and bar ball catches at a number of fixed locations on the support posts. In some embodiments, the type of attachment mechanisms for the spotter arms is the same or substantially the same as the type of attachment mechanisms for the barbell catches. In some embodiments, the user experience in operating the attachment mechanisms for the spotter arms is the same or substantially the same as the user experience in operating the attachment mechanisms for the barbell catches.
[0038] FIG. 1 illustrates a weightlifting apparatus 100 according to some embodiments. Weightlifting apparatus 100 includes first and second front support posts 105, cross member 135, first and second spotter arms 115, first and second barbell catches 125, first and second rear support posts 145, first and second post attachment stands 155, and weight holders 165. FIG. 1 also shows weight bench 195 positioned for use with weightlifting apparatus 100. Weight bench 195, may or may not be considered part of weightlifting apparatus 100.
[0039] First and second front support posts 105 are respectively attached to first and second rear support posts 145. Any attachment mechanism may be used. first and second front support post 105 are also respectively attached to first and second post attachment stands 155. Any attachment mechanism may be used. In addition, first and second rear support posts 145 are further attached to first and second post attachment stands 155. Any attachment mechanism may be used.
[0040] In some embodiments, first and second front support posts 105 are respectively integrated with first and second rear support posts 145, and respectively form first and second support post units. In some embodiments, first and second front support posts are respectively integrated with first and second post attachment stands 155, and respectively form first and second front support stands. In some embodiments, first and second rear support posts are respectively integrated with first and second post attachment stands 155, and respectively form first and second rear support stands. In some embodiments, first and second front support posts 105 are respectively integrated with first and second rear support posts 145, and are respectively integrated with rear support posts 145.
[0041] In some embodiments, weight holders 165 are omitted. In some embodiments, rear support posts 145 and weight holders 165 are omitted.
[0042] In the illustrated embodiment, first and second front support posts 105 are attached by cross member 135, which, for example, provides mechanical stability. In the illustrated embodiment, cross member 135 is attached to first and second front support posts 105 near first and second post attachment stands 155. In some embodiments, cross member 135 is attached to first and second front support posts 105 near the other ends of first and second front support posts 105 (e.g., the upper ends of first and second front support posts 105, as illustrated in FIG. 1). In some embodiments, cross member 135 is attached to first and second rear support posts 145 for example near first and second post attachment stands 155, or near the upper ends of first and second rear support posts 145, as illustrated in FIG. 1.
[0043] In the illustrated embodiment, a single cross member 135 is used. In some embodiments, multiple cross members are used. For example, in some embodiments, cross members having features similar or identical to cross member 135 may be attached to first and second front posts and / or first and second rear posts, for example, in any one or more of the locations mentioned above. In some embodiments, one or more cross members are attached near the upper ends of first and second front support posts 105 and / or first and second rear support posts 145, and are not used elsewhere.
[0044] In some embodiments, rear support posts 145 are attached to another structure, such as a wall, and no cross members are used.
[0045] First and second spotter arms 115 are respectively permanently connected to first and second front support posts 105. For example, in some embodiments, first and second spotter arms 115 cannot be removed from first and second front support posts 105 without disassembly or partial disassembly of first and second spotter arms 115 and / or weightlifting apparatus 100. In some embodiments, first and second spotter arms 115 cannot be removed from first and second front support posts 105 without a tool.
[0046] First and second spotter arms 115 are configured to support a barbell and any weight plates attached to the barbell. first and second spotter arms 115 translate the load of the barbell and weight plates to the first and second front support posts 105. In some embodiments, first and second spotter arms 115 are formed with durable material, such as steel. In some embodiments, a surface of first and second spotter arms 115 for supporting the barbell includes a thin layer of another material. The other material may include, for example, a plastic or an elastomer. The other material may be configured to protect the first and second spotter arms 115 from marring because of contact with the barbell. In some embodiments, the other material is configured to reduce noise caused by contact with the barbell.
[0047] First and second spotter arms 115 are slidably connected to first and second front support posts 105. In addition, first and second spotter arms 115 may be selectively fixed at various positions along first and second front support posts 105. first and second spotter arms 115 collectively define an adjustable barbell boundary which may be moved by repositioning first and second spotter arms 115. The adjustable barbell boundary defines a lower limit of how close the barbell can be with respect to the surface supporting the weightlifting apparatus 100.
[0048] In the illustrated embodiment, the extent to which first and second spotter arms 115 may slide along first and second front support posts 105 is limited by first and second stops 108. In the illustrated embodiment, the extent to which first and second spotter arms 115 may slide along first and second front support posts 105 is also limited by first and second barbell catches 125. first and second stops 108 may be respectively positioned on first and second front support posts 105 such that the adjustable barbell boundary defined by first and second spotter arms 115 cannot be moved closer to the surface supporting the weightlifting apparatus 100 then a predetermined distance. In some embodiments, the predetermined distance is one of about 20″, 21″, 22″, 23″, 24″, 25″, 26″, 27″, 28″, 29″, 30″, or another distance.
[0049] In some embodiments, the positions of first and second stops 108 on first and second front support posts 105 maybe changed using a tool. For example, a gym employee may adjust the positions of first and second stops 108 on first and second front support posts 105 using a tool so that the adjustable barbell boundary cannot be moved closer to an upper surface of a weight bench than a predetermined distance, such as about 6″, 7″, 8″, or another distance.
[0050] When a weightlifter uses weightlifting apparatus 100, they may conveniently position the first and second spotter arms 115 so that the adjustable barbell boundary is at a height convenient and safe for them. For example, the weightlifter may choose to position the first and second spotter arms 115 so that the adjustable barbell boundary is about one inch above their chest when laying on a weight bench. However, because of the stops, the weightlifter cannot position the first and second spotter arms 115 so that the adjustable barbell boundary is low enough that a barbell laying on the first and second spotter arms would compress the weightlifter's chest toward the bench. Accordingly, if the weightlifter is unable to lift the barbell, the adjustable barbell boundary prevents the barbell from dropping to an unsafe position.
[0051] First and second barbell catches 125 are respectively permanently connected to first and second front support posts 105. For example, in some embodiments, first and second barbell catches 125 cannot be removed from first and second front support posts 105 without disassembly or partial disassembly of first and second barbell catches 125 and / or weightlifting apparatus 100. In some embodiments, first and second barbell catches 125 cannot be removed from first and second front support posts 105 without a tool.
[0052] First and second barbell catches 125 are configured to support a barbell and any weight plates attached to the barbell. first and second barbell catches 125 translate the load of the barbell and weight plates to the first and second front support posts 105. In some embodiments, first and second barbell catches 125 are formed with durable material, such as steel. In some embodiments, a surface of first and second barbell catches for supporting the barbell includes a thin layer of another material. The other material may include, for example, a plastic or an elastomer. The other material may be configured to protect the first and second barbell catches 125 from marring because of contact with the barbell. In some embodiments, the other material is configured to reduce noise caused by contact with the barbell.
[0053] First and second barbell catches 125 are slidably connected to first and second front support posts 105. In addition, first and second barbell catches 125 may be selectively fixed at various positions along first and second front support posts 105. first and second barbell catches 125 collectively define an adjustable barbell rest position which may be moved by repositioning first and second barbell catches 125. The adjustable barbell rest position defines a position the barbell can be moved to and released by the weightlifter.
[0054] When a weightlifter uses weightlifting apparatus 100, they may conveniently position the first and second barbell catches 125 so that the adjustable barbell rest position is at a height convenient and safe for them. For example, the first and second barbell catches 125 maybe moved to a position on first and second front support posts 105 such that the barbell rest position is near the location of the hands of a weightlifter lying on a bench with arms raised. Accordingly, the weightlifter may lift the barbell so that the weightlifter's arms are straight, and the weightlifter may place the barbell in the first and second barbell catches 125.
[0055] In some embodiments, first and second spotter arms 115 and first and second barbell catches 125 are attached to the support posts by an attachment mechanism which allows for placement of the spotter arms and barbell catches at a number of fixed locations on the support posts. In some embodiments, the type of attachment mechanisms of first and second spotter arms 115 is the same or substantially the same as the type of attachment mechanisms of first and second barbell catches 125. In some embodiments, the user experience in operating the attachment mechanisms for the first and second spotter arms 115 is the same or substantially the same as the user experience in operating the attachment mechanisms for the first and second barbell catches 125.
[0056] In embodiments having weight holders 165, weight plates may be positioned thereon for storage.
[0057] FIG. 2 illustrates a side view of the weightlifting apparatus 100 of FIG. 1 according to some embodiments.
[0058] As illustrated, the visible spotter arm 115 is positioned at a maximally low location, as defined by stops 108. In addition, the upper surface of the visible spotter arm 115 is positioned above the upper surface of the weight bench 195.
[0059] FIG. 3 illustrates a portion of spotter arm 115 attached to a front support post 105 according to some embodiments.
[0060] In the illustrated embodiment, front support post 105 includes stops 108 and position indicator numerals 106.
[0061] Furthermore, in the illustrated embodiment, spotter arm 115 includes extension bar 114, surface material 112, slide body 116, position indicator window 117, handle 118, and detent actuator 119.
[0062] The surface material 112 may include, for example, a plastic or an elastomer. The surface material 112 may be configured to protect spotter arm 115 from marring because of contact with the barbell. In some embodiments, the surface material 112 is configured to reduce noise caused by contact with the barbell.
[0063] Extension bar 114 is fixedly attached to slide body 116, which at least partially wraps around front support post 105 and loosely engages front support post 105. Accordingly, slide body 116 and extension bar 114 are moveable with respect to front support post 105. Slide body 116 is fixedly attached to handle 118, such that movement of handle 118 causes slide body 116 and extension bar 114 to slide along front support post 105.
[0064] As illustrated, the spotter arm 115 is positioned at a maximally low location, as defined by stops 108. Spotter arm 115 is fixed in the illustrated position by a detent (not shown) attached to detent actuator 119. The detent is attached to slide body 116 and extends into a hole (not shown) in front support post 105. In the illustrated position, position indicator window 117 of slide body 116 is aligned with position indicator numeral 106 having a value of “1.”
[0065] To move spotter arm 115 to another position on front support post 105, detent actuator 119 is moved to a free position to cause the detent to exit the hole in front support post 105. With the detent out of the hole, slide body 116 is no longer fixed to front support post 105, and is, therefore, free to slide along front support post 105.
[0066] To fix spotter arm 115 to another position on front support post 105, slide body 116 is moved to the other position, detent actuator 119 is moved or is allowed to move to a fixed position such that the detent enters another hole in front support post 105.
[0067] As illustrated, in some embodiments, detent actuator 119 is conveniently positioned near handle 118. Accordingly, a single hand may both grab the handle 118 and simultaneously hold the detent actuator 119 in the free position. Therefore, the single hand may be used to move spotter arm 115 while fingers of the single hand hold the detent actuator 119 in the free position. In addition, the single hand may be used to hold spotter arm 115 in the other position while fingers of the single hand release the detent actuator 119 so that the detent moves into the other hole in front support post 105.
[0068] FIG. 4 illustrates barbell catch 125 attached to a front support post 105 according to some embodiments.
[0069] In the illustrated embodiment, front support post 105 includes position indicator numerals 106.
[0070] Furthermore, in the illustrated embodiment, barbell catch 125 includes J-hook body 124, surface material 122, slide body 126, position indicator window 127, handle 128, and detent actuator 129.
[0071] The surface material 122 may include, for example, a plastic or an elastomer. The surface material 122 may be configured to protect the barbell catch 125 from marring because of contact with the barbell. In some embodiments, the surface material 122 is configured to reduce noise caused by contact with the barbell.
[0072] J-hook body 124 is fixedly attached to slide body 126, which at least partially wraps around front support post 105 and loosely engages front support post 105. Accordingly, slide body 126 and J-hook body 124 are moveable with respect to front support post 105. Slide body 126 is fixedly attached to handle 128, such that movement of handle 128 causes slide body 126 and J-hook body 124 to slide along front support post 105.
[0073] Barbell catch 125 is fixed in the illustrated position by a detent (not shown) attached to detent actuator 129. The detent is also attached to slide body 126 and extends into a hole (not shown) in front support post 105. In the illustrated position, position indicator window 127 of slide body 126 is aligned with position indicator numeral 106 having a value of “22.”
[0074] To move barbell catch 125 to another position on front support post 105, detent actuator 129 is moved to a free position to cause the detent to exit the hole in front support post 105. With the detent out of the hole, slide body 126 is no longer fixed to front support post 105, and is, therefore, free to slide along front support post 105.
[0075] To fix barbell catch 125 to another position on front support post 105, slide body 126 is moved to the other position, detent actuator 129 is moved or is allowed to move to a fixed position such that the detent enters another hole in front support post 105.
[0076] As illustrated, in some embodiments, detent actuator 129 is conveniently positioned near handle 128. Accordingly, a single hand may both grab the handle 128 and simultaneously hold the detent actuator 129 in the free position. Therefore, the single hand may be used to move barbell catch 125 while fingers of the single hand hold the detent actuator 129 in the free position. In addition, the single hand may be used to hold barbell catch 125 in the other position while fingers of the single hand release the detent actuator 129 so that the detent moves into the other hole in front support post 105.
[0077] FIG. 5 illustrates cross-section view 500 showing a component 157 attached to a front support post 105 with an attachment mechanism according to some embodiments. The attachment mechanism may be used for either or both of first and second spotter arms 115 and first and second barbell catches 125. The component 157 may include a spotter arm, such as first and second spotter arms 115. The component 157 may include a barbell catch, such as first and second barbell catches 125.
[0078] In the illustrated embodiment, front support post 105 includes holes 103.
[0079] Furthermore, in the illustrated embodiment, component 157 includes component body 154, slide body 156, detent 151, spring 152, detent housing 153, handle 158, and detent actuator 159.
[0080] Component body 154 may, for example, include an extension bar 114 or a J-hook body 124, and is fixedly attached to slide body 156, which at least partially wraps around front support post 105 and loosely engages front support post 105. Accordingly, slide body 156 and Component 157 are moveable with respect to front support post 105. Slide body 156 is fixedly attached to handle 158, such that movement of handle 158 causes slide body 156 and Component 157 to slide along front support post 105.
[0081] Component 157 is fixed in the illustrated position by detent 151 attached to detent actuator 159. The detent is also attached to slide body 156 by detent housing 153 and extends into a hole 103 in front support post 105.
[0082] To move component 157 to another position on front support post 105, detent actuator 159 is moved, overcoming resistance provided by spring 152, to a free position to cause the detent to exit the hole 103 in front support post 105. With the detent out of the hole, slide body 156 is no longer fixed to front support post 105, and is, therefore, free to slide along front support post 105.
[0083] To fix component 157 to another position on front support post 105, slide body 156 is moved to the other position, detent actuator 159 is moved or is compelled to move to a fixed position by spring 152, such that the detent enters another hole 103 in front support post 105.
[0084] As illustrated, in some embodiments, detent actuator 159 is conveniently positioned near handle 158. Accordingly, a single hand may both grab the handle 158 and simultaneously hold the detent actuator 159 in the free position against the spring force provided by spring 152. Therefore, the single hand may be used to move component 157 while fingers of the single hand hold the detent actuator 159 in the free position. In addition, the single hand may be used to hold component 157 in the other position while fingers of the single hand release the detent actuator 159 so that the detent moves into the other hole 103 in front support post 105 by force of spring 152.
[0085] In some embodiments, the attachment mechanism used for first and second spotter arms 115 is substantially identical to the attachment mechanism used for first and second barbell catches 125. In some embodiments, the attachment mechanism used for first and second spotter arms 115 is different from the attachment mechanism used for first and second barbell catches 125. For example, because first and second barbell catches 125 may be lighter than first and second spotter arms 115, certain components of the attachment mechanism used for first and second barbell catches 125 maybe lighter, less strong, and / or cheaper than the corresponding components of the attachment mechanism used for first and second spotter arms 115.
[0086] FIGS. 6-8 illustrate weightlifting apparatus 100 from different perspectives, according to some embodiments.

[0103] At block 1850, the second permanent connection between the second spotter arm and the second support post is maintained while the second spotter arm is slid from the second fixed position to a fourth fixed position on the first front support post. For example, while the second spotter arm is slid from the second fixed position to the fourth fixed position, the slide body of the second spotter arm may prevent the second spotter arm from detaching from the second front support post.
[0104] At block 1860, the first and second permanent connections are maintained while the first and second spotter arms are respectively fixed to the third and fourth positions. For example, while first and second detents are moved to respectively fix the first and second spotter arms to the first and second front support posts, the slide bodies of the first and second spotter arms may prevent the first and second spotter arms from detaching from the first and second front support posts.
[0105] In some embodiments, the first and second spotter arms are prevented from additional sliding with first and second stops connected to the first and second support posts. In some embodiments, the first and second stops are positioned to prevent the barbell boundary from being closer than a predetermined distance to one or more surfaces supporting the first and second support posts.
[0106] In some embodiments, a third permanent connection between a first barbell catch and the first support post is maintained while the first barbell catch is released from a fifth fixed position on the first front support post. For example, while a detent is moved to release the first barbell catch from the first front support post, a slide body of the first barbell catch may prevent the first barbell catch from detaching from the first front support post.
[0107] In some embodiments, a fourth permanent connection between a second barbell catch and the second support post is maintained while the second barbell catch is released from a sixth fixed position on the second front support post. For example, while a detent is moved to release the second barbell catch from the second front support post, a slide body of the second barbell catch may prevent the second barbell catch from detaching from the second front support post.
[0108] In some embodiments, the third permanent connection between the first barbell catch and the first support post is maintained while the first barbell catch is slid from the fifth fixed position to a seventh fixed position. For example, while the first barbell catch is slid from the fifth fixed position to the seventh fixed position, the slide body of the first barbell catch may prevent the first barbell catch from detaching from the first front support post.
[0109] In some embodiments, the fourth permanent connection between the second barbell catch and the second support post is maintained while the second barbell catch is slid from the sixth fixed position to an eighth fixed position. For example, while the second barbell catch is slid from the sixth fixed position to the eighth fixed position, the slide body of the second barbell catch may prevent the second barbell catch from detaching from the second front support post.
[0110] In some embodiments, the third and fourth permanent connections are maintained while the first and second barbell catches are respectively fixed to the seventh and eighth positions. For example, while first and second detents are moved to respectively fix the first and second barbell catches to the first and second front support posts, the slide bodies of the first and second barbell catches may prevent the first and second barbell catches from detaching from the first and second front support posts.
[0111] In some embodiments, the first and second barbell catches are respectively positioned on the first and second support posts by third and fourth handle detents, each having a handle adjacent to a detent actuator.
