The sitting leg extensions on the stability ball is an exercise that requires pelvic stability and some awareness of what our body is doing in space as we lose one of our bases of support. Start by sitting up with your sit bones on the stability ball and try to get a little bit of curve in your low back. From this position, extend one knee by straightening the leg out and keeping the heel just off the floor. Now the value of this exercise is if you lose this base of support, the body weight wants to shift on the stability ball, but you'll stabilize through your core and trunk, getting the stability from the foot that's still on the ground. After you perform the desired repetitions on this side, you would switch legs and repeat.
