1, sit on the ground, with your legs together, your hips and heels as far apart as possible, and lean back with your hands behind your back.

2, the upper body leans forward, lifts the thigh, and the thigh sticks to the upper body as much as possible for 5 seconds. Do it three times a day, each time 10 times.

3. Stand with your legs apart, your toes facing outwards and your hands on your chest. Straighten your back muscles, bend your knees slowly, and exhale at the same time.

Keep your knees bent, then slowly move your hips down and back, bending your thighs as parallel as possible to the ground. Stand up slowly while exhaling. Be careful not to straighten your knees at once. Do it three times a day, each time 10 times.
