- Start in a plank position with your hands on the mattress.
- Pull your abs in and squeeze your glutes to stabilize your core. Inhale and bend your elbows to lower your head toward the bed; exhale, pulling your navel to the spine, and straighten your arms, returning to plank.
- Too easy? Flip your body around so your feet are on the mattress and do push-ups this way.
- Complete three sets of 10 to 15 reps (do fewer reps if your legs are elevated).
