The weather hasn't been that great around here recently, which has made me start considering getting a trainer to keep in shape even when it's raining. What kind do you recommend? I'm thinking about a fluid trainer, especially since I live in an apartment and wouldn't want to annoy the neighbors too much. My boyfriend has a 1up trainer, which I really like, but unfortunately, I don't want to spend $300 on a trainer. What has worked for you guys?
