Hello, I'm a fitness instructor. I'll tell you the truth. Leg reduction is not by practicing, but by stretching. You often stretch your calf to relieve it. Because people have to stand and walk every day, and female friends like to wear high heels, the calf muscles are always in a state of tension (that is, contraction). After a long time, the muscle fiber will grow slowly, the area will increase, the ductility and elasticity will decrease, and the calf will look thick. Therefore, it is necessary to stretch the calf frequently to strengthen the extensibility of the muscle and restore its elasticity. If a coach says he can help you practice your calves, he must be bluffing.
