This is may sound low but I just did 3 pull ups in a row for the first time ever. 💪lol
I've been training arms off and on for 1–2 years (couldn't do any before that). And then 3 weeks ago I finally got a pull up bar and have been training specifically pull ups since then.
I looked it up and apparently above 3 is strong for women, and above 8 is strong for men. The average untrained man can just do 2–3 though, so I guess I'm not too far behind.
