In continued efforts to get in shape for my mountain climb, yesterday i explored the phenomenon of "spinning" class.  For those unaware of this "class", it is basically a room full of exercise bikes and a leader who instructs you on when to go fast, when to sit or stand, and how much resistance you should have.  I have to be honest, the Scott P of his 20's would kick the snot out of the Scott P of his 30's if he had any idea he would ever entertain the idea of doing a spin class; the class, however, was actually pretty good.  It kicked my butt.  I've been running, elipticalling, tread milling, and lifting weights for five months, yet 45 minutes with this bike instructor beat me up pretty badly.  I was out of it the rest of the day.  (mind you, I also followed the class with 45 minutes of high endurance weight training).

Anywho - If you are ok with your "manliness" - give it a shot!  I plan to continue (at least until my climb is over)
