- Start on the floor, resting on your forearms and knees.
- Step your feet out one at a time, coming into a plank position.
- Contract your abs to prevent your booty from sticking up or sinking. Your spine should be parallel to the floor, with your abs pulling toward the ceiling.
- Hold for as long as you can. Aim for 20 to 30 seconds in the beginning, and work your way up to one minute as you get stronger.
