Side Elbow Plank With a Twist
This literal twist on a side plank recruits your obliques even more than a static hold.
- Start in a side plank on your right elbow, feet stacked one on top of the other. Place your left hand behind your head, elbow pointed toward the ceiling. Make sure your body forms a straight line from shoulders to feet.
- Without turning your hips, engage your abs to rotate your shoulders and reach your left elbow toward the floor.
- Hold this position for a second, then reach your left elbow toward the ceiling to return to the starting position. That's one rep.
