Do you just ride, or do you train for cycling?

If you ride a trainer, what are you training? Is it just a replacement for road time, or do you focus on particular aspects of fitness?

What about cycling-specific strength training, i.e., free weights and weight machines?

The big local club have "training rides" weekday mornings, typically 3 or 4 loops of the park (18-24 miles), which, aside from offering opportunities to just get out and ride in the morning, would be training for the cue sheet rides the club offers, some of which are leisurely, many of which are long, fast, or both, but all of which demand pace line discipline.

(edit) It's not on the poll, but another kind of training came to mind: bike handling drills - e.g., bunny hops, figure 8s, etc. I don't imagine they are the first thing that come to mind for anyone, but you might mention it if such drills are part of your training.
