Air Bike Crunches (Most Effective!)

Performed correctly:


1. Start by lying on your back with your hands behind your head.
2. Bring the thighs in at 90 degrees to your hip, and lift you shoulder blades off
the floor (without pulling on your neck).
3. Simultaneously curl your right shoulder and left knee up towards the center of
your body until your elbow and knee touch. Slowly return to the starting
position and repeat with the other side.
4. Continuously alternate sides in this ‘pedaling’ motion, for 12-16 repetitions.
