I like to wear gloves because I can't help but think of all the germs.
I used to wear padded shorts but don't bother with it anymore.
As far as the one legged pedaling, I think it goes against proper instructional methods to have the class unclip on one side but I have had instructors tell us to emphasize one leg and let the other go along for the ride.
I liked my class tonight, we were on (imaginary) cross bikes!
