Stand tall holding one end of a tight exercise band in one hand. Lift your arm up and bend the elbow to bring the band behind your back. Get hold of the exercise band with your other hand.
Gently pull the band downwards with the lower hand, bringing your upper arm up with your elbow pointing towards the ceiling. Relax and return while breathing evenly.
Note. Do not force, but increase the range of motion through relaxing your shoulder.
