- Come into a plank position with your hands placed in the center of the exercise ball.
- Bend your elbows, until you lower yourself within an inch of the ball.
- Straighten your elbows to push yourself back to starting position. Don't lock your elbows.
Do three sets of 10 to 12 reps, resting for up to 30 seconds between sets.
Trainer Tip: Play nice with your joints — never lock your elbows at the top of a push-up.
