thats funny!
But in all seriousness, i have a bike, a treadmill, and an eliptical... i almost never use the bike... just because i dont feel like im working anything, and on the treadmill... thats just running--which gets old/and in the long run, can be bad for your joints... so my vote is for an eliptical because when you're on it, you dont even really realize it and can maintain pace for the longest amount of time. Plus i sweat like a bitch on that thing
