Begin in the plank position with a DB in one hand, keeping your elbow slightly bent (so the DB doesn’t touch the floor) and your opposite hand flat on the floor. Bend the elbow of the arm holding the DB and raise your elbow to the ceiling, keeping your arm aligned with your back and release back to starting position.
Try not to push your elbow out to the sides, or bring it up too high from your back. It is important to squeeze your back muscles to raise the DB.
Stabilize your body using your core muscles as this exercise is only performed on one hand. Complete 20 reps on one side, before moving onto the final 20 reps on your opposite side.
