Lay down on your back with your feet bent and arms straight by your side. Make sure your neck is in line with the rest of your body. By pushing your hands into the ground, slowly lift your legs and lower back up until you are leaning on your upper back and shoulders.
Then, raise your hands from the ground and put them on your lower back for support while leaning on your upper arm and elbows. Start straightening your legs and put them up as high as you can.
Make sure your back is always straight and DO NOT move your head from side to side as this can result in injury.
