I have been contemplating a few ideas for winter training but can't seem to decide which route to go and would appreciate any advice. Below are the three options I'm looking at.

1. Purchase cold weather gear (due to school schedule I'll only be able to ride twice a week maybe 3x if I bike to work)
2. Purchase a membership or group of classes at a spin studio
3. Purchase a trainer (fluid)

I'm leaning towards purchasing a trainer so I can potentially put more time on the bike i.e. I can squeeze in a quick 30 minute workout when I have some downtime vs. gearing up, getting the bike ready, and going out for a ride. I can make a couple of spin classes a week before work but its a large money investment for a short return vs. a long return by purchasing a trainer.
