Men aged 30-40 have just changed their figure, gained weight, thickened external sebum and started to accumulate in the waist and abdomen. However, men of this age still have strong athletic ability. If they want to keep fit, they can do aerobic training first, such as jogging, cycling, mountain climbing, swimming and so on. Aerobic exercise can exercise people's cardiopulmonary breathing, give people a healthy heart and make people healthy and young.

In the process of fitness, we should also pay attention to gradual exercise, and gradually increase it, so that physical strength and brain can gradually adapt to avoid fatigue and physical pain the next day. Therefore, don't rush to practice physical strength and equipment from the beginning. It is best to practice aerobic exercise for about a week first, and then slowly contact the equipment after one week.

If you are a man who wants to lose weight, you should pay attention that aerobic exercise doesn't start to burn fat until 25 minutes later. 25 minutes of aerobic exercise only consumes water, salt and sugar in the body. Because aerobic exercise is generally a whole-body exercise, and the equipment is aimed at training a certain group of muscle groups in a certain part of the body, it is necessary to arrange the equipment plan according to the physical condition. For example, men with narrow shoulders can practice shoulder muscles more.
