In China, minors are citizens under 18 weeks. Gym equipment is more attractive to some adolescent boys. Some devices can also adjust the intensity during fitness, so they are also liked by some minors. Some minors use equipment to exercise in the gym and have achieved good results. However, because the vast majority of minors are not fully developed physically and mentally, they can't effectively control the equipment in the gym in terms of intensity selection and time control, so it is likely that unnecessary injuries will occur in the process of fitness, resulting in lifelong regret. So we don't approve of minors going to the gym to do equipment exercise. Minors who love sports can take part in some sports chosen by their peers, such as swimming, running and playing ball games.
