Hi all, I'm pretty new to riding. I've been riding for the last two months, about 20 miles a week, and for the last month I've been going to spinning class (3 x week) a really enjoying it. With it the days getting shorter and the weather getting colder, how do you keep in shape? Is spinning the best alternative to riding? O yeah, I'm currently 220 at 5'9" looking to get down to 180.
