Start on the floor on your hands and knees. Lower your forearms to the floor with elbows positioned under your shoulders and your hands shoulder-width apart.
If someone looked at you from the side, your arms would form a 90-degree angle. Step your feet back, one at a time.
Maintain a straight line from heels through the top of your head, looking down at the floor, with gaze slightly in front of your face.
Now, tighten your abs and hold.
