That's useless. My former fitness teacher specifically said that if you want to reduce waist fat, you should mainly exercise more, and it is best to do static exercises, such as Pilates and yoga. Don't think that yoga and pilates are both difficult sports. Their spirit is to do their best. If you want to reduce the fat on your stomach, I'll teach you a method, which is very effective. I've tried it myself. It can be easily done every day 15 minutes before going to bed. Lie flat on the bed and lift the upper body and lower body at the same time at an angle of 90 degrees for 5 seconds. Put it down and lift it up again. Do 15. The side waist must also be closed, the upper body is flat, the legs are curled up, the thighs are raised at 90 degrees with the upper body, then the legs are twisted to the left, and the upper body is kept flat for 8 seconds as far as possible, and the other side is changed. It's absolutely effective. You'll have a big surprise in a month.
