A pull-up bar is a piece of exercise equipment designed for strength training, primarily targeting the upper body. It consists of a horizontal bar that is mounted on a wall, door frame, or free-standing structure. Users grip the bar with their hands and pull their body upward, engaging muscles in the back, arms, and shoulders. Pull-up bars come in various styles, including doorway pull-up bars and wall-mounted options. They are popular for home workouts due to their compact size and versatility. Many fitness enthusiasts use them to improve their pull-up strength and overall upper body fitness.
