Because muscular legs are not obesity caused by fat accumulation, don't choose cycling, running and other sports, which will only make your legs thicker and thicker. You can choose to jog and then stretch.

If your gym has aerobics classes, I recommend yoga and Pilates.

Pilates and yoga are two kinds of exercises that contribute to plasticity ~ they can stretch the thick muscles and help them become striped muscles, thus playing a visual role in losing weight and making the legs slender.

But also remind parents that muscle weight loss is very long and painful, so parents must stick to it and don't give up after the summer vacation ~
