With all due respect b33p3r and everyone else here, to place the demands of c/s/s on yourself without being conditioned for it is the perfect formula for injury. The fact is that conditioning can be improved at any age. Yes, I am suggesting exercise. Improving your capacity and mechanics will prevent injury and raise pain free performance (also well established). But let me warm you, I listen to the objections, reasons and arguments against exercise from those who don't want to exercise every day. So if you don't agree, don't bother to post, I have likely already heard it.
