Doing simple yoga is very useful. Find a chair, hold the back of the chair with both hands, stretch your legs in turn, and lift them to the limit position for 20 to 30 seconds. Do it two or three times without any legs, and lift them forward to the outside and the inside, respectively, so as to lose excess fat on the front, back, inside and outside of the thigh. When doing these actions, you must keep your body center of gravity stable, take a deep breath and do what you can. That's what I do.
