Here's a description of the video: A man is doing preacher curls at a gym. He's using a machine made by Sterling. The machine is black and silver. The man is wearing a gray shirt with a white and black pattern, black shorts, and brown shoes. He is leaning over the padded support of the machine with his left arm extended and gripping the bar. The gym has other exercise equipment and people in the background. The floor is a gray tile.
