How to do Double Crunch

Abs Exercise Training Workout

Lie down on the floor on your back, with both hands extended behind your head. Forcefully crunch your body up whilst simultaneously pulling your knees up into your ribcage so that your chest touches your thighs. Hold it there for a brief moment and squeeze the abdominals to maximize blood flow. Slowly come back down to the original position where your arms are fully extended behind your head and your legs extended but not touching the ground (just above).
