Lie on your back with your hands behind your head. Bend your knees bringing the feet off the floor so that your calves are parallel to the earth. Keep the elbows wide as you inhale to lift the upper back off the ground and reach your left elbow to the right knee. Exhale to return to center. Inhale to reach the right elbow to the left knee. Alternate sides for several rounds.
Practice with ease rather than intensity. Keep the chin slightly tucked and the chest open.
Builds and balances agni.
