The wall is provided with a second protrusion, and a rotation gap of the first protrusion is provided between adjacent weight plates; the first protrusion is arranged vertically from top to bottom, and the second protrusion is arranged spirally from top to bottom; or the first protrusion is arranged spirally from top to bottom, and the second protrusion is arranged vertically from top to bottom; the pull rod is provided with an adjustment mechanism for driving it to rotate, and the first protrusion is matched with the corresponding second protrusion by rotating the pull rod, and the weight plates above the matching position serve as the weight resistance of the movement. The disadvantage is that: while the trainee is expanding his chest, the whole body is not effectively stretched, and only part of the body is exercised, the exercise effect is poor, and it has certain limitations. Summary of the invention

[0003] The technical problem to be solved by the present invention is that most of the existing training equipment exercises local parts, lacks the ability to stretch the whole body at the same time as local movements, and the training effect is poor. In order to improve its shortcomings, the present invention provides a linkage push-up trainer.

[0004] To achieve the above object, the present invention is achieved through the following technical solutions:
