So I recently watched an interesting video. The Youtuber explained how he learned to master pull ups. He said we should pick a number of pull ups that we want to get done in a single session -- for example, 10. You might be able to get in only 2 or 3 at a time, but you just get 10 done even if this means doing a bunch of sets of only 1. I like this idea! So I've incorporated it into my weekly workouts. As you can see here, I perform a set of 2 pull ups with good form, then take a brief break.
After that I do another set of 2, then another set of 2 until I've reached 10. By the way, nothing wrong with a band for assistance if you need one.
Enjoy this rainy day!
