Weighted Crunch Up

Muscles

Target

* Rectus Abdominis

Synergists

* Obliques

Stabilizers

* Hip Flexors

Instructions

Preparation

Lie supine on mat or floor with bench leg and arms pointed up.

Execution

Flex waist to raise upper torso from floor. Return until the back of the shoulders contact the padded incline board. Repeat.

Comments

Hip may move slightly during exercise. Exercise can be performed with added resistance if needed by holding weight above. Quadriceps were not listed under stabilizers since they are not under significant resistance. Certain individuals may need to keep their neck in a neutral position with a space between their chin and sternum. See Arm Position During Waist Exercises and Spot Reduction Myth.
