In the past when I did dips, I always went until my upper arm was parallel with the ground. However, within the last 3 months, doing this caused shoulder pain and a minor shoulder injury. Soooo.....take that for what it is worth.
On a side note, which Stuart McRobert book are you reading?

I am not a powerlifter nor am I a bodybuilder. I just want to be big and strong.
