Action: Trunk stabilization, spinal flexion, knee and hip flexion, shoulder stabilization

Major muscle groups involved: Abdominals, quadriceps, hip flexors

Execution:

Walk out to your prone bridge, hands on the ground, lower legs or feet on top of the ball (depending on your fitness/ability level). Make sure that your arms are completely perpendicular to the ground, not angling back toward the ball. Simultaneously flex your hips and knees, pulling your knees forward toward your chest. As your knees travel forward slightly lift your hips and flex your spine. Do not allow your torso to drift back toward the ball. Return to the starting point by fully extending your knees and hips.
