Windshield Wiper

The Windshield Wiper is a variation of hanging leg lift that strengthens the internal obliques.

Begin hanging with your shoulders up by your ears (elevated) and legs held at the top of a hanging leg lift.
Be sure your toes are touching the top bar in the V position.
Now begin to lower your straight legs to your right side, keeping your toes just off the wall.
Continue to lower down until your feet are level with your hips, twisting through your torso.
Fight to keep your left hip close the wall as your legs drop down.
Pause briefly in the bottom, raise your legs back up to center, and switch sides.
Continue to alternate sides for reps, pausing in the V between each.
