This exercise focuses on isolating the biceps as much as possible, trying not to carry out the shoulder extension. To do this, perform closed grip pull-ups, bringing the elbows out and with a partial range of travel, from fully stretched until the crown reaches the bar. Try not to separate your body back during the execution of the exercise, always keeping your head under the bar.
