Bicycle crunch

How to do it

1. Lie on your back with your hands behind your head and legs raised and bent.
2. Lift your shoulder blades off the floor by contracting your abs.
3. Bring one elbow toward the opposite knee while extending the other leg.
4. Alternate the movement, rotating your torso to bring the other elbow to the opposite knee.
5. Keep a controlled pace, focusing the rotation in the obliques, not pulling the neck.
