Side Plank for a Strong Core
Begin lying on your right side on the floor. Place your right hand directly below your right shoulder. Keeping your body and legs straight lift your body up off the floor. Hold for a count of 10-15, and then release. Repeat lying on your left side. Lift and hold for 10-15 seconds, then release. For more of a challenge, hold your top arm straight up, perpendicular to the floor, with your palm forward.
