five people doing exercises on a sandy indoor beach volleyball court. The sand is tan. A volleyball net is in the background. The people are spread out across the court. The person closest to the camera is a woman. She is wearing black leggings and a gray crop top. To her left is a man wearing black pants, a patterned gray shirt, and a bald head. Behind him is a man in a burgundy t-shirt and black shorts. To the left of the man in burgundy is another woman in a white shirt and dark pants. Further to the left is another man wearing a black t-shirt and shorts. All are doing the same exercise, raising and lowering one arm at a time. There are several volleyballs in the left background of the video. The room is enclosed in a white dome-like structure.
