@dollfaceme23 Used to be in a similar shoes as you in the beginning of this year. I struggled so dam hard with pull ups and the known given tips such as using bands, doing negatives, or even inverted rows just weren't helping me at all much I got impatient and was about to call it quits until I forgot there was still another grip variation. I was actually able to do supinated grip (aka chin ups). I've decided to change my grip and do underhand grip for chin ups instead as it still works your back muscles very well as standard overhand grip pull ups with the only different with it is having some bicep work for chins. After weeks/months of practicing only with chin ups for awhile, slowly my reps were increasing. I was able to do 3, then about 6, and now I can do 8 in a row! I always focused on executing full range of motion and sometimes pausing on top to get a good mind muscle connection to have more back muscle focus and less bicep work. In the beginning I do about 6 sets of 3, then 6 sets of 6, and now I do 4-5 sets of 8. I was also doing inverted rows otw to strengthen my back more to focus on my scapula movement. After progressing perfectly well with doing chin ups, I tested myself out to do pull ups, and I was actually able to do proper full range of motion form of pull ups by 4 reps! Not alot, but better than nothing?
So, from my take here, if supinated grip/underhand are an easier grip variation for you to execute than pronated/overhand, stick with doing CHIN UPS instead in the beginning so you can strengthen your back to progress for standard pull ups. Also you should still continue doing inverted rows for support too! Importantly when you do your reps, make sure you're depressing your scapula as you go up and don't try to round your back. Instead try to arch instead as it's an ideal form that will work your back very well, though it's still okay to do them in a hollow form. Another tip to get you have good mind muscle connection, pause at the top for some seconds gripping the bar hard and focus most of the tension contracting the back muscles more than the biceps so you don't just get a bicep focus only chin up. Lastly be sure to squeeze your glutes and tighten your core muscles along with point your feet down that way you wont be swinging so much during reps.
Hope this gives you some ideas and helps for your progress. Best of Luck!
