Start in a small squat. Jump sideways to the left, landing on your left leg. Bring your right leg behind to your left ankle, and don't let it touch the floor.
Make sure your back is flat against the wall. Place your feet firmly on the ground, shoulder-width apart, and then about 2 feet out from the wall. Slide your back down the wall while keeping your core engaged and bending your legs until
they’re in a 90-degree angle.
