Fitness steps can straighten and stretch muscles.

1. Stand on the ground with your hands clasped with your fingers, and try to keep your palms touching the ground. (hold for 2 minutes)

2. Sit on the ground, straighten your legs, and lean your head on your thigh as much as possible to help pull the ligament. (Press three times a day)

3. Sit on the ground with your legs apart and your head on your thigh. (twice a day, one minute each time)

4. Stretch before going to bed. (Hold for one minute)

If you insist on doing the above points every day, you will get better slowly.
