Second, take a chair that is almost as high as your knees and put it behind you. Put the toes of your left leg on the bench. Kneel down your right leg to drive your body to bend your knees and try not to exceed your toes. Inhale when squatting, exhale when getting up, and do 15 times, alternately counting left and right as a group.
Third, put your legs together, lunge to the left, raise your hands horizontally in front, sit back on your hips, retract your left leg, lunge your right leg, and repeat the action. Do 15 times on one side first, and then change 15 times on the other side as a group.
