In a well-lit indoor gymnasium, three young men are exercising near a badminton net. On the left, a person dressed in a white martial arts uniform is performing arm stretches. To the right, a person in a red t-shirt and red shorts is seen mirroring the same stretches. Further to the right, a third individual in a dark long-sleeved shirt and white pants is also participating in the exercise. Piles of purple mats are stacked behind the person in white on the left. The gym has a yellow wall with a dark-colored door and visible windows.
