Place the ball on your thigh against the wall
Stand on your inside leg. Your toes should point forward and lifted up. Find support on the small toe side of your sole.
Raise your outside foot, place a little bit front of the inside foot and flex your ankle (toes up).
Square your pelvis (or the outside hip can be a little bit front)

1. Lower your body until you can hold the balance
2. Extend your legs
