Description

Technical Field

[0001] The utility model belongs to the technical field of training equipment, and more specifically, it particularly relates to a pull-up training device. Background Art

[0002] Pull-up is not only a training action to exercise upper limb muscle strength, but also a suspension strength exercise that overcomes one's own gravity with one's own strength. Moreover, it is the most basic method to exercise the back. When policemen conduct daily physical training, they all use pull-up training devices to strengthen the muscles of the back. Based on the prior art, it is found that the existing pull-up training devices lack auxiliary training structures. When novice policemen use pull-up training devices for training, they all need to use assistance bands to complete the training. If they do not carry elastic bands during training, they cannot use pull-up training devices to train the back; and the existing pull-up training devices lack structures to assist novices in finding the best grip distance. When novice policemen conduct pull-up training, they often cannot quickly adjust to the ideal grip distance. Therefore, they need to adjust when holding the horizontal bar. However, due to the poor grip strength of novice policemen, after spending time adjusting each time, they are too weak to do pull-ups anymore. Summary of the Utility Model
