What systems have any of you used/thought up/heard about that may let one effectively exercise whilst at the computer? I know you can do about anything in front of the TV, but I don't sit in front of the boob tube that long, but rather at the 'puter.
Ideally I'd like to be able to use an elliptical traininer whilst at the computer, with the ability to type, mouse, etc still intact. (Clearly, I'd have to take my hands off the handies thingies to type and mouse: that's OK.) Anyone gerryrigged anything that works for that? Or anything else?
(I hope that natural-born-engineer Frenata's reading this...)
