Here are the steps to do the worm:
1. Lie down flat on your stomach on soft ground. Choose an open area where you'll have plenty of space to move.
2. Keep your toes flexed up toward your body. The tips of your toes should be pressed firmly into the ground when you start.
3. Place your hands on the floor under your shoulders with your fingers pointing toward your feet.
4. Push up with your hands and lift your chest off the ground.
5. Arch your back and lift your legs off the ground.
6. Push off with your toes and slide forward on your stomach.
7. Lower your chest and hips back down to the ground.
8. Repeat steps 4-7.
