Instructions
Preparation
Lie supine on floor with lower legs on exercise ball. Extended arms out to sides. Straighten low back, knees, and hips, raising back and hips off of floor.
Execution
Keeping hips and low back straight, bend knees, pulling heels toward rear end. Allow feet to rollup on to ball. Lower to original position by straightening knees. Repeat.
Comments
Keep hips straight throughout movement. Dorsal flexion of ankle reduces active insufficiency of Gastrocnemius allowing it to assist in knee flexion.
