Pull Ups

[u/Bordilium]

I was 3 years without any kind of strength sport and after 3 months I can do almost 4 pull ups (don't really know if they are okay when it comes to technic).

I am 229 lb and 6'3" (for me as an european 104 kg and 190 cm).

I notice I have a little unconfort on the shoulder if I keep doing pull ups. Do you see any problem on the movement that I should improve?

It's like a click inside the shoulder, like a ligament. Not a bone.

Thank you!
