... resisting desire to comment on Calamari's pushmepullyou...

I've always used rollers, though I do find them extremely boring. I much prefer being outside for winter so I do a lot of nordic skiing which does a great job of keeping your entire body in shape (I think I'm often in better shape at the end of winter than at the end of summer). One complaint with my rollers is that I can't vary the resistance. So, I'm thinking about getting a trainer for this winter (I'll still ride rollers, if nothing else for form), prob either a TACX or KURT.
