Ive been doing assisted pull ups for about 6 months slowly working down to less band assistance. I do 3x10 on my vertical push pull day. I started a few weeks ago doing neutral grip chins without bands on other days and have had no problems. Usually do 3x4-6.
I did regular chinups today and had a discomfort in the posterior part of my upper arm. It doesnt feel like tricep pain but it could be. I was wondering about the insertion of the lats and whether this new angle for me is too stressful? I did 3x3.
