In a standing position place the stability ball on your back up against the wall.
It should reside between your upper back and helps contouring your natural spinal
curvuture. Place one leg out in front of you a reasonable distance and one leg behind
you close to the wall. This is just like the regular squat only in this exercise your
front leg will perform most of the lift. Slowly lower yourself until the front and
rear leg have come close to or just past 90-degrees. Now push hard with the front
leg to return to the starting position. After finishing your set, switch legs and
repeat.
