I used to be able to do 15-16 consistantly, and my record was 20. I injured my shoulder in November 2014, and it's only just finishing healing now. As a result I'vr lost a lot of strength in the last year. I have no idea how many I could do now - maybe about 10? 

This is my favorive exercize so my best result is 22. These days I can do no more then 18

Uh,....3.

Well pull ups, that is quite hard!

yours?
