SIDE PLANK OBLIQUE CRUNCHES
- Lie on your side, with your elbow bent to 90* directly under your shoulder.
- Push yourself up to support your weight, creating a nice straight line from your foot to your shoulder.
- Place you spare hand on the side of your head.
- Crunch down-over, aiming your top elbow down towards the floor and squeeze the life out of your obliques.
Obliques, abs, lower back.
