I've said that I use it for excercise, driving home takes 15 minutes and my cardio workout takes much longer. I get home 5-10 minutes later and get half of my cardio done that way. I'm a college student and only have a certain ammount of time to use sparingly. Being a weightlifting biking freak I have to lift and ride my bike a lot or I go nuts. I have thought of taking a cycling class at my gym with some coworkers to just show how good of shape I am in by commuting but decided not to. I could easily do that class, I think and then drive home but I just don't feel like it. I'm on winter break and I have gotten maybe 4 days where I didn't have to ride in 90 days so I think 2 days of rest are a necesity as much as possible to help my muscles recover and get ready for another 90 days of commuting constantly. As for being crazy, hell when summer time comes having the most cut up body out there will turn heads and change minds :-)
