This action is very simple. Put your hand down and replace it with an arm to support your body at 90 degrees. Keeping your body in line is like doing push-ups. Hold this position and breathe slowly twice!

2. Chair style:

First of all, keep standing, put your feet together, chest out and abdomen in. Then slowly squat down your hips, just like sitting in a chair, and at the same time slowly extend your arms upward, stop when you reach the highest point (pay attention to the shoulder width of your arms) and start exhaling. Keep this posture and breathe evenly for 5-8 times.

3, arch bridge type:

Put your hands back on the ground, tilt your right leg backwards and keep balance with your left leg, then straighten your feet, keep your hands forward and move your feet backwards until your hips are tilted and your arms are away from your ears. Keep this posture and breathe evenly for 5 times.
