A young woman in a green tank top and black leggings is performing a seated triceps extension exercise at the gym. She is seated on a black weight bench, gripping a straight bar attached to a weight rack. The bar is loaded with weight plates. Her hair is pulled back into a bun. She pulls the bar down in front of her chest, isolating her triceps muscles. The gym has a blue floor, various other weight machines, and a few other people working out in the background. The walls are dark, and there is a fan circulating the air.
