I remember a few years ago when I incorporated them into my training I could do maybe 4 reps (bodyweight) @ best! Now I can crank out 9 easy! 10-12 possibly. it definetely helps having your own squat rack @ home and whenever you feel like gettn a quick pump just jump up grab the pullup bar & go to town! My bar isn’t completely straight though. It straight in the middle but then has a few bends in it like a lat bar. So when I do my pullups I use an overhead(prone) wide grip.
I also like doing thumb - thumb (touching) prone grip pullups. These realy works your brachialis! And to fox it up ill throw a close grip neutral row attachment over the bar and do them. Ill even put the rope attachment over and do pullups with the rope! Man these are fun! Hopefully 1 day I can get to 20 bodyweight prone wide grip pullups!
