As a general rule, a narrow grip works the biceps more, while a wide grip requires more work from the latissimus. With tight pull-ups, you can also increase the effect on the biceps by performing them with an underhand grip (palms facing you) instead of an overhand grip. The multifunctional pull-up bar also allows you to perform pull-ups with a particularly ergonomic parallel grip, allowing you to get the most out of your muscles.
