Upper body: Caterpillar plank

*More challenging

Standing with feet shoulder-width apart, bend forward at the waist and place your hands on the floor; crawl forward to plank position with shoulders directly over wrists. Bend elbows to lower your body toward the floor, then push back up.

Next, bend your left knee, bring it up and in toward your chest, then rotate your waist as you raise your bent left leg out until it’s parallel to the floor. Return to plank and repeat on the opposite side. Return to standing.
