A young man performs walking lunges with dumbbells in a gym. He wears a dark patterned T-shirt, black athletic shorts, and colorful socks and athletic shoes. He holds a dumbbell in each hand, and the dumbbells appear to be eight kilograms. The gym has wood-look floors and a glass wall with a brick wall behind it. There are people visible in the reflection of the glass wall. A logo with the word "KAYB" is visible on a wall to the left.
