Time to work our core with an easy plank variation.
Lay down on the floor with your belly to the ground. Align your elbows directly below the shoulders and ground the toes into the floor. Lift your body up and align your butt, upper back and head in a straight line. Keep a neutral neck and spine.
Keep your head facing down, and extend one arm. Hold the position as long as you can, without shifting your hips.
