If you are familiar with performing a traditional elbow plank, try this new variation for an extra challenge to your core muscles. Just remember to make your movements very small in order to keep it safe and effective.
Begin on all fours. Position your elbows directly below your shoulders and place your hands and forearms flat on the floor, shoulder-width apart. Straighten your legs behind you. Balance on your toes and forearms as you bring your hips down to shoulder level. Keep you knees straight and press your heels back. Pause for two breaths.
