How many pull ups/chin ups can you do?
 

:)
pull ups=17
chin ups= 19
I can just pump out the chins easier
I'm going for the middle school record of 22:thumbsup: :D

thats really good. pull ups are hard. ive worked pretty hard at it and on a good day i can do 18 mabye 19 like u

my numbers have recently shot up (arm hair? lol)
pull ups are more of the back being used.....chins are more bicepes...i think

alot of how many pull ups you do is form. not always strength. i suck at pull ups 3 for me. my frined can do like 20 and when we lift my back is way stronger in dead lift, pull downs, and rows

well lat pull downs doesn't really convert to pull ups....same with deads.... rows are more for the back too.

Which are which? lol

Does the grip with plams in mean chin up and palms out mean pull ups? Or is it just how high you go on the bar?

chin=palms facing you
pull ups= palms away from you

I can do 19 pull ups and 15 chin ups. I'm only 15. :)

How do you think i could improve?

do you have wide hand spacing on the pull ups? because you use more back with wide arms making you be able to do more.
add weights;)

to improve, just do them as part of your workout. if you lift weights the pull up should be the back part of your workout. i have a good friend who had no access to weights but had a pull-up bar. when he started he could do 15 maybe 20 reps. i told him to do 100reps. he laughed saying it was'nt possible. then i told him to do 100reps, but take as many sets as required to get it done. that could mean 20 sets or more. if you have do do 10sets of 10reps, do that. you may have to do a some sets of just one or two reps. i would argue against adding weight unless you want to use the exercise to gain mass.
