Seated dumbbell curls in progress at the gym

Three young men are seated on blue chairs in a gym, performing dumbbell curls. The man on the right, wearing a black t-shirt and a red, white, and black beanie, is the closest to the camera. He holds a dumbbell in each hand, with his arms bent and weights lifted towards his shoulders. The man in the middle, wearing a white t-shirt and black shorts, is performing the same exercise. The man on the left, wearing a black t-shirt with blue accents and black shorts, is also engaged in the exercise. All three men are looking forward, focused on their workout. The gym environment includes various weight machines and mirrors in the background. The floor is a light wooden laminate.
