Lying Side Crunch
- Body weight
1) Lay on your side and bring your knees closer to your body. Your hips and knees should both be at 90 degrees.
2) Place your hands behind your head.
1) Curl up towards your tailbone by tightening the core - you'll feel this in your obliques.
2) Pause, 'crunch' and breathe out at the endpoint. Now, slowly lower yourself to the starting position.
