The movement is in 4 parts, starting with the beginning position (A). On count 2 rotate the hands at the wrists so that the fingers point straight forward (B) On count 3 return to the original position (A), and on count 4 rotate the wrists so that the fingers point straight backwards (C). The elbows will rotate. Move in a rhythm of one full cycle per 4 seconds. Keep the arms straight and continue for 6-7 minutes, inhaling in position A, exhaling in positions B and C.

Continue the motion powerfully and always keep the arms parallel to the floor when in position A. Continue for 1-2 minutes.
3) Stand up and add Crow squats to the arm movements of exercise 2. As you exhale come down into Crow Pose, a crouching position with the knees drawn into the chest and soles of the feet flat on the floor (A). As you inhale and bring the arms up over the head. come into a standing position.
