Instructions
- Preparation: Hook feet under support and lie supine on floor or mat with hips bent. Hold plate behind neck. Execution: Raise torso from floor by bending waist and hips. Return until back of shoulders contact with floor or mat. Repeat. Comments: Feet can be held down by partnerinstead of foot bar. Exercise can be performedwithout added weightuntil more resistance is needed. Exercise can be performed onincline boardto increase resistance or decline board to decrease resistance. Certain individuals may need to keep their neck in neutral position with space between their chin and sternum. If upper back does not come completely down at end of movement, abdominal muscles may only beisometricallyinvolved in exercise. Pectineus, Adductor Longus, and Brevis do not assist in hip flexion since hips are already initially bent.
