Stabilization - Patent pending pelvic stabilization system utilizes adjustable foot brace which allows the user to "lock into" the hip pad, causing hip extensor engagement for optimal pelvic stabilization.

Lumbar level axis of rotation - Promotes the use of the lower back (spinal erectors) as the prime movers. Starting positions provided every 10°.

Adjustments - The adjustable footbar accommodates user height variation.

Lumbar pad - Promotes proper and controlled movement into extension. Curved lumbar pad encourages lumbar extension/flexion while minimizing the possibility of excessive extension.
