How to do: Oblique Crunches - On The Floor

Step-by-step instructions

1. 1Start out by lying on your right side with your legs lying on top of each other. Make sure your knees are bent a little bit.
2. 2Place your left hand behind your head.
3. 3Once you are in this set position, begin by moving your left elbow up as you would perform a normal crunch except this time the main emphasis is on your obliques.
4. 4Crunch as high as you can, hold the contraction for a second and then slowly drop back down into the starting position.
5. 5Remember to breathe in during the eccentric (lowering) part of the exercise and to breathe out during the concentric (elevation) part of the exercise.
