Fat guy's dance

A group of people, including a man in a black tank top and white cap leading the class, perform synchronized aerobic exercises on a patio with step platforms, while others in swimwear and robes follow the routine; the participants step onto and off the platforms, swing their arms, and move their legs in unison, with a man in a black speedo on the left performing exaggerated movements. The setting is an outdoor area with palm trees, closed umbrellas, and lounge chairs.
