[0020] like Figure 1-4 The forearm muscle strengthening training device shown includes: The stool surface 1 is long and narrow, and its length is supported by the support frame 2 and the legs 3. The stool surface 1 provides support for sitting posture and reduces spinal pressure. The support frame 2 and the legs 3 are fixedly connected to the stool surface 1.

[0021] Preferably, the bottom surfaces of the support 2 and the legs 3 are respectively provided with anti-slip layers to ensure stability.

[0022] Two barbell loading components 4 are symmetrically arranged on the outer side of the bench surface 1; the two barbell loading components 4 are symmetrically arranged about the bench surface 1.

[0023] The barbell loading component 4 includes a slide rod 41 that is vertically slidably connected to the support 2. The middle part of the slide rod 41 is vertically slidably connected to the support 2. The top end of the slide rod is located above the support 2, and the bottom end of the slide rod is located outside the support. The barbell loading component 4 also includes a positioning ring 40 fixedly sleeved on the slide rod 41 and a handle that rotates on the slide rod 41. The support 2 is preferably made of iron pipe and serves as the mounting base for the barbell loading component 4 and the bench surface. The support 2 has a section of axially continuous hollow tube that is not grounded. The bottom end of the hollow tube is at a certain height from the bottom surface, and the middle part of the slide rod 41 is sleeved inside the hollow tube. The rotation axis of the handle is along the width direction of the bench surface.

[0024] Multiple weight plates 5 are loaded at the bottom of the slide bar 41. The weight plates 5 can be separated from the slide bar 41. Each slide bar 41 has a handle 43 rotatably connected to its top. The handle 43 is covered with a handle glove 44. The handle glove 44 is preferably made of rubber.

[0025] The barbell plates 5 can be detached from the slide bar 41 to enable the slide bar 41 to be configured and adjusted, providing adjustable external resistance. The training intensity can be adjusted by changing the length of the gravity arm and the load mass. Loading the barbell plates 5 onto the slide bar 41 is prior art, as can be seen in Chinese Utility Model Patent Application No. CN201921087188.2, "Outdoor Back Muscle Trainer"; or Chinese Utility Model Patent Application No. CN202220993391.1, "An Adjustable Barbell Plate System"; or the bottom end of the slide bar 41 is a horizontal crossbar with external threads at both ends, and nuts are threaded to both ends of the crossbar. Multiple barbell plates 5 can be fitted onto the crossbar, and then the multiple barbell plates 5 are fastened and positioned by the two nuts. When using, the barbell plates are loaded according to the user's needs, with an initial recommendation of 5%-10% of body weight.

[0026] The handle 43 includes a horizontal tube rotatably fitted onto the top of the slide rod 41 and a vertical tube fixed to the horizontal tube. The straight line containing the two horizontal tubes is along the width of the stool surface. The horizontal tube supports 360° rotation around its own axis, accommodating dorsiflexion, palmar flexion, and radioulnar deflection movements. The horizontal tube has only rotational freedom relative to the top of the slide rod 41, with the axis of rotation along the width of the stool surface. The top of the slide rod provides a horizontal fixed rod with a length along the width of the stool surface. Each horizontal fixed rod has annular protrusions at both ends. The horizontal rod 43 is fitted over the horizontal fixed rod and confined between the two annular protrusions. A vertical tube is fixed to the horizontal plate 43.

[0027] When subjected to external force, the slide bar 41 can be lifted or lowered. When it falls, the bottom surface of the positioning ring 40 abuts against the top surface of the bracket 2, preventing the slide bar 41 from moving vertically downward.

[0028] When using, in extension / palm flexion mode: hold the horizontal tube of the handle and lift the slide bar 41 to a preliminary suitable position as needed, and then perform wrist rotation (extension) and wrist flexion (palm flexion) movements as needed, with the weight of the barbell plates providing resistance.

[0029] Radial / ulnar deviation mode: Hold the handle and slowly lift the slide bar 41 vertically as needed to stimulate the coordinated contraction of the radial / ulnar muscle groups. You can also rotate the vertical tube around the axis of the horizontal tube as needed to exercise the wrist and forearm.

[0030] Preferably, the handle 43 is T-shaped. This way, when the hand grips the vertical tube of the handle, the hand rests against the bottom surface of the horizontal tube, making it easy to lift the slide rod. The handle 43 can also be a 7-shaped handle with a 90° bend.

[0031] Preferably, the slide bar 41 has the following structure: it includes a vertically fixed vertical rod and a horizontal rod located outside the support 2. The middle part of the vertical rod is vertically slidably connected to the support 2, and multiple barbell plates 5 are loaded on the horizontal rod. The top of the vertical rod has a 90° bend, and the horizontal fixed rod formed after the bend is located inside the two supports, used to rotatably connect the handle 43. The slide bar 41 has an overall Z-shaped structure with two 90° bends. The barbell plates 5 can be fitted onto the horizontal rod, and the end of the horizontal rod away from the vertical rod is provided with external threads. A nut is threaded to the end of the horizontal rod, which can clamp the barbell plates 5 between the nut and the vertical rod.

[0032] The support 2 is equipped with a hollow tube. The interior of the hollow tube is hollow, meaning it has through holes that slide with the vertical rod. The vertical ends of the vertical rod pass through the through holes, thus achieving a vertical sliding connection between the vertical rod and the support 2. The horizontal rod is vertically fixed to the bottom end of the vertical rod.

[0033] Preferably, the positioning ring 40 and the slide rod 41 are fixedly connected as follows: the positioning ring 40 is threaded onto the outer surface of the slide rod 41, located at the upper middle part of the vertical rod. The positioning ring 40 is similar to a nut structure, forming a protrusion that extends beyond the slide rod 41. Its outer diameter is larger than the through hole, serving a limiting function. Located on the top surface of the bracket 2, it prevents the slide rod 41 from falling out of the through hole. By adjusting the position of the positioning ring 40 relative to the slide rod 41, the vertical height of the handle is controlled, adapting to different training height requirements and people of different heights. During use, the handle is adjusted to a 90° elbow flexion position.

[0034] Preferably, the structure of the bracket 2 is as follows: it includes a grounded base 21, which can be I-shaped, including a pair of parallel horizontal plates and a middle plate perpendicular to the two horizontal plates, thus increasing the grounding area. Multiple support rods 22 for fixing and supporting the stool surface 1 are fixed on the base 21, and support frames 23 are fixed to both ends of the base 21. The sliding rod 41 is slidably connected to the support frames 23.

[0035] The upper part of the support frame 23 is a hollow tube that slides around the slide rod 41. The lower part of the support frame 23 is fixed to the base 21 by an inverted V-shaped reinforcing plate. The two branches of the reinforcing plate are fixed to the same end of the two horizontal plates, and the top of the reinforcing plate is fixed to the outer surface of the bottom end of the hollow tube. The support frame 23 serves to strengthen the connection between the base and the seat 1.

[0036] Preferably, two foot pedals 7 are fixed on the support 2, distributed on both sides of the width of the bench surface 1. The foot pedals 7 are preferably inclined, tilted towards the handle, and positioned below the handle. The foot pedals 7 restrict lower limb movement and concentrate force on the forearm. Through the rotatable handle, dynamic resistance adjustment via barbell plates, and the ergonomic support structure provided by the bench surface and foot pedals, a complex movement of wrist dorsiflexion, palmar flexion, and radial-ulnar deviation can be achieved. This device can comprehensively activate the forearm flexor and extensor muscles and the synergistic radial-ulnar muscles, promoting balanced muscle development and improving wrist joint stability. It is suitable for sports training, rehabilitation medicine, and daily fitness.

[0037] Preferably, the handles 43 are located on the side of the support 2 closest to the bench surface 1, and the barbell plates 5 are located on the side of the support 2 furthest from the bench surface 1. This arrangement allows for sufficient space to load the barbell plates 5.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
