You have to know your body fat content, subcutaneous fat content and muscle content, and then decide your exercise amount and make an exercise plan.

Generally speaking, skin relaxation will occur during fat-reducing exercise for the following reasons:

Excessive exercise, a lot of water loss in muscle parts, protein and even muscle fiber damage. Therefore, a reasonable exercise plan is necessary, and the plan should be based on your understanding of your body. Just do a single test.

Do not pay attention to a balanced diet before and after exercise, diet or even improper diet in order to lose weight. For dieters with more body fat, women should supplement collagen, crude fiber and vitamins every day, while men should supplement whey protein and crude fiber food. At the same time, it is recommended to eat more fish, beef, chicken, oats and fruits with low sugar content.

The sports are too single. For example, in order to reduce abdominal fat, only do supine, running, exercise bike and other sports. Without assisting other parts of the body, the whole body fat consumption is unbalanced, and the stretching effect of muscles and skin is unbalanced. For example, running with aerobic exercise for a long time, riding a bicycle and lying on your back, but not doing squats, so that the abdominal fat will go down, but at the same time, the muscles of the arms, waist and abdomen will also be damaged, unable to support the skin epidermis, and there will be a large area similar to stretch marks. At this time, we should not only supplement protein, but also strengthen anaerobic exercise. All-round and whole-body exercise program planning is very necessary for dieters.
