Hi,

I haven't been paddling in a few years, and now I'm getting back
into taking a kayak out. Not far, just a half mille or so now. It
feels hard on my shoulders. I dislocated my left one a few years
ago in some fairly fast water. It doesn't really feel much different
from the way the other one feels due to recent paddling though.

Is it hard on the rotator cuff just doing basic paddling in a lake?
Are there excersises I can do to make the shoulders stronger?
If I just paddle and don't do anything else, can it do more harm
than good? So far I don't even stretch out before or after, how
important is that and what/how to stretch?

Thanks for any help!
David
