A muscle-up is an advanced strength training exercise that combines a pull-up and a dip. It involves pulling the body up over a bar or rings until the chest is above the surface, followed by pushing down to extend the arms and complete the movement. This exercise primarily targets the upper body, engaging muscles in the back, shoulders, and arms. To perform a muscle-up, one must have a solid foundation in both pull-ups and dips. Proper technique is crucial to avoid injury and maximize effectiveness. Many athletes use muscle-ups to enhance their overall strength and improve performance in related activities, such as gymnastics or calisthenics.
