A group of people participate in an exercise class inside a studio. The camera records the scene through a window, the word "STUDIO" printed in white lettering on the glass. The room has red walls and a gray floor with white lines. About ten individuals are visible in various exercise outfits. They are performing a high-knee exercise, with legs kicking high and arms bent at the elbows. Water bottles are scattered along the wall behind them. The lighting is bright.
