[0002] The rowing pull-up is a rowing exercise, specifically a seated pull-down. When performing the rowing pull-up, the practitioner typically sits with dumbbells or a barbell in hand, legs shoulder-width apart, and back straight. To begin the movement, the dumbbells or barbell are raised from abdominal position to shoulder height, then slowly lowered. This exercise works multiple muscle groups, including the back, shoulders, and arms. For beginners, rowing helps develop back muscle control and motor skills, while also improving back strength and stability. When performing the rowing pull-up, it is necessary to use... The existing rowing pullback trainer uses an old-fashioned movable shaft structure with a snap-fit ​​arm for forearm stretching, which may cause the bearing housing to break during exercise, posing a safety hazard.

[0034] Please see Figures 3-5 A second handle 211 is fixedly connected to the vertical plate 201, and bearing seats 212 are installed at both ends of the fixed shaft 106.

[0035] In one specific embodiment, the second grip 211 facilitates gripping and provides a guiding effect, and the connection between the bearing seat 212 and the forearm 209 can improve the smoothness of the forearm 209 rotation.

[0036] Please see Figures 3-5 The lower end of the forearm 209 is fixedly connected to two buckle plates 221, and the fixing shaft 106 is installed in the lower opening groove of the two buckle plates 221.

[0037] In one specific embodiment, the buckle plate 221 facilitates protection of the bearing seat 212 from both sides, while improving the stability of the fixed shaft 106.

[0038] Please see Figure 6 A reinforcing plate 311 is fixedly connected to the front end of the support plate 301, and a foot pad rod 312 is fixedly installed at the lower end of the support plate 301.

[0039] In one specific embodiment, the reinforcing plate 311 can help improve the connection strength between the limiting component 300 and the mounting bracket 101.

[0040] Please see Figure 6 The pad 302 is made of pure cotton.

[0041] In one specific embodiment, the cotton pad 302 is relatively soft, which can improve the protection of the trainee's chest.

[0042] Working principle: During use, the trainee's chest is against the pad 302, which protects the trainee's chest. The seat cushion 305 provides support. Height adjustment is achieved by simply rotating the adjustment lever 306 clockwise or counterclockwise, which raises or lowers the seat cushion 305 along the grooves 304 on the surface of the toothed plate 303. This height adjustment enhances the versatility of the trainer. The buckle plate 221 secures the bearing seat 212 from both sides. Since the fixing shaft 106 is fixed... The fixed structure avoids the situation where the bearing housing 212 breaks during training, which is similar to the situation with movable shafts, thus improving training safety. At the same time, by stepping on the foot pedal 208 and pressing the extension rod 207, the third pull rod 206 can be stretched. Under the tilting effect of the second pull rod 205, the mounting plate 204 can stretch the first pull rod 203 and its end, the forearm 209 connected to the vertical plate 201, so that the forearm 209 is closer to the trainee, so that the trainee can maintain a seated posture for training operations, thus improving ease of use.
