Begin in plank position with your shoulders over your wrists and your torso in one straight line.
Keep your abs engaged as you slowly walk your hands out in front of you. Go as far as you can while maintaining a tight core without your hips sagging down. As you get stronger, you'll be able to walk your hands out farther, with the goal being to touch your nose to the floor!
Slowly walk your hands back to plank position. This counts as one rep.
