Long-term swimming will make thin people grow strong and fat people thin. In short, their bodies will become very symmetrical. Swimming in the water for a long time because of the high resistance, the whole body will exercise and form muscles. The muscles you meet will make boys look strong, but they will not be fat.

Swim 3-5 times a week, at least 1 hour each time, and the effect should be more obvious in about 2 months. But swimming should control the diet and not let the muscles turn into fat.
