sideways floor sit-up

Step 1. Right side lying down, legs on top of each other. Make sure your knees are slightly bent.

Step 2. Place your left hand behind your head.

Step 3. Once you are in this set position, begin by moving your left elbow up as you would perform a normal crunch, but this time the main emphasis is on your obliques.

Step 4. Crunch as high as you can, hold the contraction for a second and then slowly drop back down into the starting position.

Step 5. Remember to breathe in during the eccentric (lowering) part of the exercise and to breathe out during the concentric (elevation) part of the exercise.
