Start in a plank position on a matted floor, and with your elbows on the mat, extend your body to its full length. Move one arm at a time to lift yourself into a standard push-up position. Then, keep your back straight and move back into a plank position. Repeat three sets of eight repetitions.
Rev it Up: Add Medicine Ball Tosses
Begin in a shoulder-width stance, holding the medicine ball at navel level. Rotate the trunk, shoulders, arms and head to one side as far as you can, then twist back into the opposite direction. You can do this exercise with a friend, but if you're working out solo, be sure to twist and aim toward the upper corner of the room as you contract down. Be sure to focus on rotating the feet, hips, and shoulders first.Read MoreLess
