Waist reduction on both sides: 1. One is to shake the hula hoop (aerobic exercise lasts for 30 minutes before you start to consume fat, so exercise for at least 30 minutes). After a week, you obviously feel that both muscles are tense.

2. Stand with your feet slightly wider than your shoulders, your arms flat and your body "big". Then bend your back, touch your left ankle with your left hand, then stand up straight and switch to the right. When you do it, you will feel the muscles on both sides of your waist stretched. Do a group of left and right, do 30 a day.

If you don't have much time, I suggest you do some stretching exercises mentioned above. There's another one. I used it. It's very useful. The simplest thing is to straighten your arm, up, and then to the side, doing eight or nine eight beats a day.
