How to do it

1. Sit on the floor with your knees bent, feet flat and hands placed behind you, fingers pointing toward your feet.
2. Press through your palms and heels to lift your hips until your torso forms a tabletop, then kick one leg out and up in front of you.
3. Bring the foot back down, keep your hips high and kick with the other leg.
4. Your hips set the standard for every rep - the moment they sag toward the floor, the exercise stops being a plank and starts being a sit.
