Stability Ball Push-ups
Get Set: Begin with your hips on the ball, hands on the floor and feet stretched out straight behind you. Walk hands out a bit so that the ball is positioned either below the thighs or, to make it more difficult, below the ankles. Place hands on floor in line with shoulders.
Work: Lower body by bending elbows, bringing the chest as close to the floor as possible. Make sure to keep head, torso and legs aligned and tight. Straighten arms to complete rep.
Variation: If the stability ball push-up is too challenging, try kneeling push-ups on the floor or a plank hold for 30 seconds (with or without a stability ball).
