Biking to nowhere

I did it: I bought a NordicTrack SL 700 exercise bike. I knew that I was going to have to invest some money to sufficiently motivate me to get off my ass and away from the computer, TV, etc. And now my muscles are all a quiver from putting the thing together (not quite as light or easy as my Sears salesman would have me believe -- Jen, Pam, and I took all the parts out of the box in my driveway and took the pieces up the stairs). I may be too wiped out from assembly to actually use the thing tomorrow.
