Primary Muscle: Abs
Equipment: Bodyweight
Level: Advanced
Purpose: To taget the lower abs.
Execution: Gasp the chin-up handles with a narrow neutral grip. Lift yourself off the ground by bending at the elbows and leaning back slightly. Keeping your body upright and your legs straight, lift your legs up all the way driving through your abs. You want to lean back as you lift your legs and bring your knees into your chest. Be sure to squeeze your abs and fully exhale your breath at the top of each breath. Straighten your legs before slowly lowering yourself to the start position.
