heh, I meant my response to sound more flip than it was -- I never DID seriously consider grading while working out, but I don't know it came out that way in my post!
baffled -- a "particular form of torture" -- what a fitting way to describe it! I hate to say it, but in my experience, it doesn't get any easier!
I think you're right about the guy who grades on the recumbent bike... but then, he probably doesn't care about not grading, or working out, well!
