Core: Elbow Plank and Reach
Adding an arm reach to your elbow plank forces the abs into high gear as they work to keep the torso steady.
- Begin in an elbow plank with your feet slightly wider than your hips to create more stability.
- Reach your right arm straight out, with the thumb pointed toward the ceiling. Return back to elbow plank, and reach your left arm out. This completes one rep.
