Pull ups are tough for everyone. Some of us works to get 1 pull up, some of us works to string pull-ups together, some of us works on efficiency and some of us works on other styles…etc… The best way to get better no matter whichever level we are at is to work on strict pull ups. I attached a video at the bottom. Hope it help.
