Hips lie on your back against the wall, hands are raised horizontally, legs are opened to the side, knees are straight, legs are extended inward, and each exhalation deepens. Starting from the inverted arrow, bend your right knee to spread your knees, put your right ankle on your left thigh, bend your left knee and hip outward, step on the wall with your feet, and your thighs are close to your abdomen, with your hands on your sides and palms up.
