1. Sit on the ground with your feet straight, your back tilted, your hands supported, and your hands rested on your hips. Press the lower back to the ground, raise your legs to 45 degrees with the strength of your abdomen, and put your toes forward so that your feet and calves are in a straight line and your legs are close together. Draw 12 circle clockwise, and then draw 12 circle counterclockwise.

2. Pick up a dumbbell with both hands, support it with your right foot, and put your left foot a few inches behind you. Keep your back straight and your hips lean forward until your body is almost parallel to the ground and your dumbbells are in line with your shoulders. Return to the starting position and complete the whole action. Repeat the action 12 times, and then practice on the other leg.

3. Open your feet 45 degrees outward, with the distance between your feet wider than your hips, and then slowly squat down. From this position, step your left foot outward and keep squatting. Take a step to the right, then resume the initial action and continue to cross the crotch. First cross 10 step to the right, and then cross 10 step to the left. This action can not only thin the calf, but also thin the lower abdomen.

4. Stand naturally, with your feet shoulder width apart, lift two dumbbells weighing 5- 15 Jin, put them on your shoulders, and put your palms forward. Bend your knees slightly, keep your body straight, and then slowly bend your hips until your upper body is parallel to the ground. Keep this action for 5 seconds, and then return to the original state. Repeat the action 8- 10 times.
