Stand erect, keeping the distance between the feet about one or one-and-a-half feet. Raise your right hand towards the sky and look towards its, palm. Keep your left hand down. Now pull your right hand up and left hand down by stretching your body and inhaling.
Now exhaling lower down slowly towards left, without bending your legs, in such a way that your left palm should touch the ground on the side of your foot. Keep on exhaling your breath during the process of lowering. Keeping your right arm close to your ear, make it parallel to the ground, looking all the time towards the sky. Now revert to the first position while inhaling the breath. In this position, stretch both your hands up and down.
Repeat this process with your left hand up and right hand down.
