A person with long dark hair, wearing a black tank top and black pants, performs a muscle-up exercise on a pull-up bar. They begin by hanging from the bar with their arms extended. They then pull themselves up, bending their elbows, and transition their body over the bar, ending in a dip position with their arms bent and their body above the bar. They then lower themselves back down to the starting position. The exercise takes place in a gym, with gym equipment visible in the background.
