How to do the oblique crunches - on the floor
- Start 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.
- Place your left hand behind your head.
- Once 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.
- Crunch as high as you can, hold the contraction for a second and then slowly drop back down into the starting position.
- Remember to breathe in during the eccentric (lowering) part of the exercise and to breathe out during the concentric (elevation) part of the exercise.
Muscles worked
The prime movers are the rectus abdominis and the obliques, which flex the trunk forward and resist it being pulled into extension or twisted out of line.

How this movement works
One joint changes angle and the resistance travels toward you along a single arc. Nothing is positioned to help, so tension stays where you aimed it and the usable load drops sharply against a multi-joint pull for the same muscle. Protect the range of motion; buying weight by shortening the arc defeats the point.
It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.
What you need
No equipment at all. The resistance is your own bodyweight, so you progress by changing leverage, range or tempo rather than by adding plates — and you can do it anywhere.

Difficulty
Listed at beginner level: the pattern is simple enough to pick up without coaching, and a position that goes wrong mid-set is obvious enough to correct on the next repetition.
