Instructions

Preparation

Hook feet under padding and lie supine on incline bench with hips bent. Hold plate behind neck or on chest with both hands or use no weight.

Execution

Flex and twist waist to raise upper torso from bench to one side. Return until the back of the shoulders contact the padded incline board. Repeat to the opposite side alternating twists.

Comments

Exercise can be performed without added weight until more resistance is needed. See Arm Position During Waist Exercises. Elevate incline to increase resistance. If no knee support is built in to the incline board, a ball can be placed under the legs as illustrated.

Hip and knee flexors may be involved as stabilizers if incline is steep and no calf support is used. See Spot Reduction Myth.
