You've already received some great advice but definitely take advantage of spin class. I really got into it this year when a little mom and pop opened in my town and I started going regularly. It's made me a much better cyclist as I really polished up on my endurance and resistance. Granted, I'm not exactly a great cyclist per se, but spin class just prepared me for the past season and I'm still going. Definitely, heed the advice of the experts and get to know your own saddle/bike. Best of Luck!
