I've decided that this year that I'm going to be in good cycling condition before the warm weather hits. I signed up for a spinning class (offered by the PE department of my university) that meets for 45 minutes a day twice a week. Since the spinning will be pretty much all of the cycling I'm able to do until a) it doesn't get dark at 4pm and b) the temperature gets above 20degrees do any of you have any tips? I've never tried spinning before ... are there any ways I can get the most out of it for my cycling purposes? I assume that the teacher will be knowledgable about cycling, but there will probably be lots of people taking the class who just want to get in better shape and not necessarily for cycling. Any comments would be appreciated.
