Thin belly has been exercising for a few days and feels that her stomach is really small. Is it psychological? It is particularly painful to review at the beginning of exercise. Turning the hula hoop will make your stomach red and hot. Dear, the place to turn the hula hoop is our waist, which is the watershed between the upper and lower bodies. This place is the only side rib around the human body. Long-term massage and exercise, dredging meridians can improve the waist line. I suggest that you can reasonably match your diet and do some yoga exercises to stretch your muscles, so that you can lose weight step by step.
