My answer is colored by your locations, Morgantown WV. I used to work up near Deep Creek Lake and my memory is that you get quite a bit of snow up there. So, where, in most places, winter clothes would help you get outside (where you will make the most improvement), I would say, get a trainer (1up, Kurt K, etc.) and suck it up. Trainers generally blow but, with the right distractions (iPod, movies, college bb games) you should be able to get through at least an hour or two a day.
