A shirtless man is exercising his triceps in a gym. He has a short, shaved haircut and is wearing blue shorts. He's standing in a bent-over position, leaning slightly forward, and pulling a cable attached to a weight machine. The machine has a 20kg weight plate on it. The man is performing triceps extensions, focusing on isolating the muscles in his arms. The gym is well-lit with overhead fluorescent lights, and various exercise machines and equipment are visible in the background. The floor has a textured, rubberized surface. The camera angle captures the man from a side view, showing his posture and arm movements during the exercise.
