Based on health channel, pull-ups are considered a classic exercise in bodyweight training. Building back strength in pull-ups requires tight form without using momentum in lifts, according to Men’s Journal. Pull-ups don’t rely on your biceps to help you through the movement. Therefore, pull-ups force the other muscles of your back to push you up the bar (through the barbend).
It also means that pull-ups are very difficult if you don’t have a strong back, according to live strong. After all, how can you progress with pull-up exercises? if you can’t do it? Using a large resistance band can help lead you to the bar. Because of the overhand grip, pull-ups can also cause shoulder discomfort, especially if your shoulders are already tight. Normally, our shoulders can become tight by bending over at a desk all day, causing them to rotate internally. This made it difficult for us to target the lats without injuring the shoulders. Therefore, if you’re doing pull-ups, be sure to warm the soft tissues around your chest so that your shoulders can be exposed (via Men’s Journal).
