"Pronated Pull-Ups" is a video demonstrating an upper body exercise where you hang from a pull-up bar with your palms facing away from your body (pronated grip) and pull your body upwards until your chin clears the bar. This exercise primarily targets the latissimus dorsi (lats), along with the muscles of the upper back including the rhomboids and trapezius. Pronated pull-ups also engage the biceps and forearms for stabilization and grip strength. The video typically focuses on proper form, technique, variations, and the benefits of incorporating pronated pull-ups into a strength training routine to build upper body strength, improve pulling ability, and promote overall back development.
