How to do: Step Through Side Plank

Start on your hands and knees with your shoulders directly on top of your wrists. Shift your weight to your left hand and lift up your right hand as you slide your left leg underneath you and out to the right side. You'll know you hit the right spot when your torso is open to the right side of the room and your right arm is lifted up toward the ceiling. Unwind and return to a high plank as you perform the same thing on the other side.
