Crunch (arms crossed)

Instructions

Preparation

Lie supine on mat with lower legs on bench. Cross wrists on chest.

Execution

Flex waist to raise upper torso from mat. Keep low back on mat and raise torso up as high as possible. Return until back of shoulders contact mat. Repeat.

Comments

Leg elevation keeps pelvis tilted back, keeping low back on mat. See Spot Reduction Myth.

Easier

Movement can be made easier by placing arms further down away from head or extended up above knees. Deconditioned individuals can start on slightly declined board.

Harder

Exercise can be made more challenging by placing hands further up toward head. See Arm Position During Waist Exercises. Exercise can also be performed on incline board or with additional weight.
