Reduce the fat and steps of thighs and buttocks, and try to keep your legs too high! Not too fast, an hour and a half. The flesh of the waist and back, with feet shoulder-width apart, twist back, slowly, turn to your limit, hold for 10 second, and then in the opposite direction for 20 minutes every day.
It's a bit like yoga. Stick to it and I'll be careful and effective!
