>>81477489 (OP)Pull-ups are extremely hard, just keep at it, it took me weeks to do a single one.
2 years later and I still struggle to do more than a handful, it's one of those exercises that requires you are either strong enough to move your weight, or skinny enough to where you can do them with ease.
Most bodybuilders who don't do them can't do a single one, that's the kind of exercise it is, I'm not even joking.
Pull-ups are retarded hard unless you're very skinny, keep working at it, OP.
I got here with negatives, and then slow reps, and now I launch myself up and then slowly lower myself to get the most out of the movement.
