A pull-up bar is a simple piece of exercise equipment designed for strength training. It consists of a horizontal bar that is mounted at a height allowing individuals to hang from it and perform pull-ups or chin-ups. This exercise primarily targets the muscles in the upper body, including the latissimus dorsi, biceps, and trapezius. Pull-up bars can be found in various forms, such as doorway bars, wall-mounted bars, or free-standing units. They are popular in home gyms and fitness centers due to their effectiveness in building upper body strength and improving grip. Regular use can enhance overall fitness and contribute to better posture.
