1, stand, with one leg back as far as possible, sole on the ground, back leg straight, front leg bent and body vertical. Try to pull your arm back. Hold on for 8- 12 seconds, change legs and do it again.

2. Stand, with one leg stretched forward and kept straight, the hind legs bent, the body slightly leaned forward, and the arms raised horizontally in front of the body. Hold on for 8- 12 seconds, change legs and do it again.

3. Stand still, lift one leg, grab both feet with both hands, and try to get close to your hips. Keep your hips balanced, your knees together, and your upright legs slightly bent. If you have trouble keeping your balance, you can hold the wall or chair. Hold on for 8- 12 seconds, change legs and do it again. Do it again after skipping rope.
