Power Crunch (by Gainz)
- Body weight
1) Lay on the floor and extend your arms and legs in opposite directions.
1) Curl up by tightening the core - come all the way up so you're balancing on your tailbone. As you do this, lift your arms and knees towards the ceiling. Have a 90 degree angle in the knees - heels keeping contact with the floor. Pause, 'crunch' and breathe out in the centre.
2) Now, gently lower yourself back to the starting position.
