...and don't "just ride" on the trainer or stationary bike. You'll be miles ahead (literally) come spring if you have a specific goal and workout in mind every time you get on the trainer. Build climbing strength? Long, low-rpm, big-gear intervals. Increase cruising speed? Tempo intervals. Recover from last night's killer workout? Easy spin. There are plenty of specific, carefully-choreographed indoor cycling workouts available online and in books at your local library. And IME, these workouts won't let you get bored.
