What's a trainer? You guys... *ahem*... hunnies... are talking about them for winter training, and I'm curious. I have a hard time riding in the winter because the cold, dry, pacific northwest air makes breathing painful. So can someone link me something or post a pic? I'm interested because biking was gonna be my main exercise for getting fit for teh wedding, but it just didn't happen. Now I have 5 months and I'm nowhere near my goal, and I need something to do inside the warm, cozy, breathable condo.
