SETUP: Lie on your side with your elbow on the ground, directly below your shoulder. Push yourself up to support your weight, creating a nice straight line from your foot to your shoulder.
REP: Place you spare hand on the side of your head, and crunch down-over, aiming your top elbow down towards the floor so you can squeeze the life out of your obliques.
TIP: You can easily switch to a standard Side Plank Hold from this exercise.
