Good place for my first post after lurking for a year lol.
Echoing what others have said about neutral grip pull ups. I started getting tendinitis when I began weighted chin ups so I had to stick with low intensity body weight chin ups with neutral grip for about a week. I also iced my biceps just above the elbow pretty regularly, which seemed to help. Now that I don't do anything but neutral grip I haven't had any issues.
