Rolling Side Plank

Get into a side plank position. Lie on your right side with legs out straight, stack your feet and brace yourself on your right elbow and forearm. Raise your hips off the floor using your obliques so that your body is in a straight line from your feet to your head. Hold in the up position for a second or two, then roll over onto your left side and drive right into a left side plank—bracing yourself with your left elbow and forearm, your right foot stacked on your left. Continue holding the plank and rolling onto alternating sides for 30 seconds.
