Instructions
- Preparation: Place feet under foot bar or low overhanging stationary object. Lie supine on floor, mat, or sit-up bench with hips and knees bent. Place hands behind neck. Execution: Flex and twist waist to one direction while raising torso from bench by bending hips. Return until back of shoulders contact floor or mat. Repeat to opposite side alternating twists. Comments: Feet can be held down by partnerinstead of foot bar. 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. SeeSpot Reduction Myth.
