A group of people are participating in a boxing exercise class on a rooftop. There are around 15 people, a mix of men and women. Most are wearing black athletic clothing, and they are standing in a sandy area. The participants are mimicking boxing punches, following instructions from an instructor, who is wearing a red headband. A few people are watching the class. Behind the group are several tall, white pillars. In the distance, there is a city skyline and a view of the ocean. The sky is partly cloudy. There are some wooden poles stuck in the sand, seemingly as part of the exercise setup. The video is taken from the perspective of someone standing among the participants.
