Every workout, especially ones like pull-ups, needs a good warmup. It prepares your body for hard work, helps you do better, and lowers the chance of getting hurt. The exercises we picked - Banded Overhead PullApart, Banded Horizontal Pull-Apart, and Banded Pull-Downs - work your back muscles, shoulders, and arms. These are the muscles you use most in a pull-up. We've noticed that most people have weaker back muscles than their front muscles.
