It's amazing how many excuses people manage to come up with for how it's impossible for them to follow this kind of advice. Turns out, it's impossible up until the point that you just shut up and start doing it. Sweating is only a problem for most of you because you're unhealthy and overweight. You're overweight because you get no exercise. It's okay: I was too. Then I started cycling to work and lost 50lb. Now sweat…
i'm pretty sure that if you do not sweat after a 20min ride that covers 7.5mi, you should seek a doctor. Urgently. ...or you are luck to live on the top a hill and work in a dried lake bed.
20 minutes was my _record_, with me hauling ass as fast as I could possibly go. And for the record, I was drenched. But I brought a change of clothes and had a quick shower that day. :)
