In the video, a man is seen working out in a gym. He is wearing a red tank top and black shorts. The man is using a cable machine to perform tricep extensions. He is standing in front of the machine and pulling the handle down towards his body while keeping his elbows close to his sides. His arms are fully extended at the end of the movement. The gym appears to be well-equipped with various exercise machines and weights in the background. The lighting in the gym is bright, and the walls are painted in a neutral color.
