A group of people are doing a warm-up exercise with an instructor. The instructor is a woman with red hair, wearing a black t-shirt and grey and black tie-dye leggings. The other participants are a mix of men and women. Some are wearing t-shirts and shorts or leggings, while others are wearing workout clothes. The room has green artificial turf flooring and a blue and orange sign on the wall that reads "Interval." Some exercise equipment, including blue mats, is visible in the background. The instructor leads the group through arm exercises including raising the arms overhead.
