TECHNICAL FIELD
[0001] The utility model belongs to body -building equipment technical field, and specifically points to the training is used to pull the back muscle training device. BACKGROUND
[0002] The back muscle training device is a common body-building equipment, mainly used for exercising back muscles, and is usually composed of a seat, a pull rod, a pulley system, and a counterweight. The conventional pull back muscle training device is relatively large in size, and is usually arranged in a professional gym. For ordinary fitness enthusiasts, the existing pull back muscle training device is not suitable for ordinary families to purchase and use because it occupies a large space. In addition, the consumption in the gym is a considerable expense. In modern society, people have a fast pace of life, and the distance to and from the gym will take up some time. Moreover, the gym is an open environment, and many people will feel social pressure when exercising in the gym, which makes many people reluctant to exercise in the gym. The above problems also discourage people's enthusiasm for exercising.
[0003] The current back muscle training device can adjust the training weight by increasing or decreasing the counterweight, but it does not have height and position adjustment. If the exerciser exercises on the body-building equipment that does not match his or her own physique, the body will exert a lot of force in an uncomfortable state, which can easily cause muscle strain, bone wear and tear, and joint sprain, etc. At the same time, the exercise effect is not good, which increases the risk of injury and also cannot achieve the expected shaping effect. SUMMARY
[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a pull back muscle training device for training, which solves the problems of large size, inconvenient storage, and low applicability of the training device in the prior art.
