Standing Side to Cross Crunch

Instructions

1. Stand tall with hands behind your head and elbows wide.
2. Lift one knee out to the side while crunching your elbow toward it (side crunch).
3. Return to start, then drive the same knee up and across your body while twisting the opposite elbow to meet it (cross crunch).
4. That is one rep; continue on the same side or alternate as prescribed.
