Miss Liz talked about weight training a few times and I'd like to echo what she said about cross training. It's really important to keep muscle mass, therefore bone mass, at an optimal level. I weight train 3-4X/week, a "push/pull" split. I really love it because it isn't boring, you can get through it fairly quickly and it really works. Plus, when serious cycling starts in the Spring, you'll be amazed how much stronger your legs are uphill.

Also, I'd much rather have defined arms than the bird arms I see on the aerobic bunnies in the gym. (oooh...was that out loud?)
