Re: Broken Clavicle - Advice sort
My advice would be, when you do finally eventually get healed enough to go back, ask around different people about how they first learned rolls. Some ways may be safer than others, and some people explain it or show it better than others. E.g., I'm assuming you're learning to roll from kneeling initially (or kneeling on one knee I guess I mean), that you've been shown how to use your arms so there isn't an impact on your shoulder (I've even seen variations of different ways to do that), etc...
The way we learn rolls at the beginning at my dojo I actually find it kind of hard to imagine how someone could generate enough force to actually break a bone. But then maybe I'm just underestimating.
