A group of about a dozen people are exercising on what appears to be a rooftop. The roof has a sand-like surface and is surrounded by tall, white pillars that frame a view of the ocean and cityscape in the distance. The participants are dressed in athletic wear, mostly in light colors, black or white. They are performing a choreographed boxing-like routine, led by an instructor who is wearing a black shirt and a red headband. They are all facing in the same direction, and seem to be in sync with each other and the music playing in the background.
