How to perform the Abdominal Crunch
| Technique |
- Lie on the floor with your legs bent, your feet flat on the floor. If you prefer, you can keep your legs bent at a 90 degree angle so that the bottom of your feet are vertical.
- Place your hands on the back of your head, or if you prefer, cross them over your chest.
- Lift your shoulder blades off the ground moving your elbows towards your knees. Don't try to lift your whole back - just your shoulder blades.
- Squeeze your abs for a second.
- Slowly return to the starting position.
- Repeat steps 3 - 5 until you've completed the desired number of reps.
|
| Number of Reps |
3 sets of 25 reps. Try adding weight if you find this too easy and you're trying to build muscle size/strength, or, if you're not trying to build muscle size, just increase the number of reps.
