A woman is performing a back extension exercise on a Roman chair in a gym. She is wearing purple leggings and a purple and white t-shirt. Her feet are secured by red pads, and her hips are resting on a red padded bench. She is leaning forward, with her torso extended, and then arching her back to bring her torso back up. The gym is equipped with various weight machines and free weights. The lighting is bright, and the overall environment appears clean and well-maintained. There are other people visible in the background, also engaged in their workouts.
