Hello, my friend, I graduated from college for three years, and my weight has increased by 20 Jin compared with that when I graduated. At this time, through proper fitness, you can achieve the effect of shaping and firming, lose too much fat on your body, make your body slimmer and your muscles firmer. Not only that, but also the phenomenon of facial skin relaxation will be improved.

The best way to lose weight by exercise is to do low-intensity, rhythmic and long-lasting aerobic exercise, such as jogging, brisk walking, dancing, martial arts, skipping rope and swimming.

If the time is too short for half an hour, the intensity is too high, the cardiopulmonary function of the body is not strengthened, the heart rate can't go up, and the oxygen supply of the body can't meet the needs of exercise, then the body exercise belongs to anaerobic exercise.

In the process of anaerobic exercise, the body only consumes sugar and fat is not mobilized, so short-term exercise can not achieve the effect of losing weight and lowering blood fat.

With the passage of more than 20 minutes, the heart rate rises and the cardiopulmonary function is strengthened. The oxygen supply of the body can meet the needs of exercise and meet the needs of the body. The body participates in aerobic exercise. In the process of aerobic exercise, the sugar and fat in the body can be fully metabolized, and excess calories and fat are consumed, which has a good effect of losing weight and lowering blood fat.

So a healthy way to lose weight is still very important. The whole body fitness will not affect the chest. Fitness will make the skin firmer, but it will not affect the size of the chest.
