Pull-Ups are a type of strength training exercise that primarily targets the muscles in the upper body, particularly the latissimus dorsi, biceps, and trapezius. To perform a pull-up, an individual hangs from a horizontal bar with an overhand grip and pulls their body upward until their chin is above the bar. This exercise can be modified by using different grips or adding weights for increased difficulty. Pull-ups are commonly used in fitness routines to build muscle strength and endurance. They can be performed in various settings, such as gyms or home workout spaces, and require minimal equipment. Regular practice of pull-ups can improve overall upper body strength and contribute to better performance in other physical activities.
