mostly the outer part of my shoulder and about 1/3 way down towards the biceps... ive tried different positions and and the pain lessens the wider my grip is but then the weight tends to slip lower down my back so i have no choice but to bring the grip closer... i mean its bearable but im sure theres a way to get rid of it unless this normal for all squatters..?
Yea some discomfort can be normal for squats. I've had my arms go numb doing high rep squats with a close grip.
Make sure you are not trying to "hold" the weight with your arms. You want to be "pulling" the bar into your back.
