I've been practicing like 40-50+ hours a week the last month and a half without my back bothering me one bit, and as soon as I posted about my back on the forum in response to Fatboys comments, my back goes out.....LOL... Oh well,,,, I'm not blaming you at all fatboy, this is just a joke... Not about my back it really is out, I just hate to not be able to practice as much when I'm starting to really get back into stroke....
