Setting the arms at different levels means you can deepen your push-up one arm at a time to work the pecs even more.
- Start in a plank position with your left hand on a medicine ball.
- Keeping your torso square to the floor, perform a push-up by bending and straightening both arms. If a traditional push-up is too challenging, lower your knees to the floor.
- Start with five reps on the first side, then move the med ball to the other hand.
