Cobra Pose

Lie down on your belly. Extend your feet so their tops touch the floor. Place your hands on the floor under your shoulders. Elbows close to the trunk.
Straighten your arms and push your upper body of the floor. However, your lower body, from the belt down, should maintain contact with the floor.
Hold the pose from 15 to 30 seconds breathing slowly. Release from the pose and lie down on your belly.
