In the gym, in addition to running, a large part of the equipment is for upper limb strength training. The existing upper limb strength training equipment often uses the method of adjusting different numbers of counterweights to adjust different training intensities. During the training process, the counterweights move up and down. Due to different habits of each person, the pulling frequency is different during the pulling process. Some people pull too fast, which may cause muscle damage, and pull too slowly, which will affect the effect of the exercise.

[0003] Existing upper limb muscle endurance training equipment often adjusts different training intensities by adjusting different numbers of counterweights.
