In the video, a man is seen wearing a blue shirt and gray pants. He is standing in front of a gray background and is demonstrating how to stretch the shoulder muscles. He starts by extending his arm out to the side and then bending it at the elbow to bring his hand towards his shoulder. He repeats this motion several times, alternating between extending his arm out and bringing it towards his shoulder. The man appears to be speaking and explaining the process as he performs the stretches.
