- Start face down on the floor resting on your forearms and knees.
- Push off the floor, raising up off your knees onto your toes and resting mainly on your elbows.
- Contract your abdominals to keep yourself up and prevent your booty from sticking up.
- Keep your back flat — don’t let it droop or you’ll be defeating the purpose. Picture your body as a long straight board, or plank.
- Hold as long as you can. Aim for 20-30 seconds in the beginning and work your way up to one minute, as you get stronger
- Repeat for three sets
