First, it is not suitable for beginners. For beginners, it is easy to use gym equipment aiming at a certain muscle physiological characteristics, but it is difficult to find the feeling of training by self-weight training. If you choose the self-respect of beginners, it is recommended to buy a systematic book for self-study or it is best to find a fitness instructor to guide you first.
Second, it is not suitable for people who are too thin and do not reach the standard weight. The reason is very simple, their self-weight is too small ... Using their own weight training will turn strength training into aerobic training, and the training intensity will be greatly reduced.
Third, it is not suitable for women who want to modify their figure and practice their parts. Because women's fitness requirements are often very detailed. Generally speaking, chest training will reach the shoulders and buttocks will reach the legs, but most girls want to practice chest stiffness but don't like deltoid muscles, and want to practice buttocks but don't like thick legs, so it is more suitable for them to design gym equipment isolated for a certain muscle group.
