With the body lying on the floor, the legs are stretched back with thighs and feet touching the floor. Back is arched and chest is lifted, supported by the hands, which are underneath the shoulders. Don't: Get the chest up too high. Some people tend to push their arms straight, thinking they'll naturally assume a deeper and more advanced version of this pose. But this makes the shoulders start to move up toward the ears, putting strain on the shoulders.
