1. Stand up.
2. Bend down and touch the ground with your hands. Bend your knees if you need to.
3. Start inching your hands out in front of you. Your feet remain in place. You will be moving your hands farther and farther out in front of you. More and more weight will be on your hands.
4. Once you have extended yourself as far as you can go, keep your hands still and start inching your legs forward until they meet your hands again. Try to keep your knees straight.
