Most of us who workout regularly know the benefits and the importance of doing pull-ups regularly. CrossFit even mentions it in this article.
As a physical therapist and a strength coach, I do not encourage the violent movement from the Kipping Pull-ups exercise. I've treated many patients over the years with Upper Trap Strain and Shoulder Injury as a result from doing the Kipping Pull-ups from CrossFit.
My question is why do Kipping Pull-ups in the first place? Also, if you are a CrossFit lover or a Certified CrossFit Trainer, how should I approach you without you thinking that I'm against CrossFit philosophy?
