1. Lie on your stomach, flat on the floor. Push up onto your forearms.
2. Bend your elbows and rest your weight on your forearms.
3. Keep your elbows under your shoulders.
4. Pull your belly button towards your spine.
5. Your body should form a flat line. Don’t let your hips sag, and don’t push your butt up—keep your body in a straight line.
6. You can do this plank on your hands instead of your elbows if you prefer (if you feel any pain or stiffness in your wrists, balance your weight on your elbows instead).
1. Lie on your side with your legs straight and your body in a straight line (shoulders and hips stacked one on top of the other; don’t lean forward or backwards).
2. Prop your body up so your hips are off the floor. Rest your weight on the elbow on that’s touching the floor.
3. Only your forearm and feet should touch the floor.
4. Do not let the hips sag—this is the challenging part of this move. As you get tired, you’ll want to drop the hips, but focus on keeping them stationary.
