Personal Trainer Darrick Kung demonstrates a Three-Point Plank. This exercise strengthens the hip and oblique muscles and reduces the risk of lower back and shoulder stress.
Start in a push-up position with your feet shoulder-width apart.
Bring one arm off the ground and to your hip, shifting your weight to remain in push-up position. Hold for 30–60 seconds.
Gently return your arm to the starting position.
Repeat with your other arm, again holding for 30–60 seconds. Rest after both arms are done. Repeat three to four times on each arm as you are able.
