I've been wanting to start some weight training for a while now, and I've been gathering info about what sorts of muscle groups to work on. I took weight training all through university as my physical education course so I've got a good handle on technique and so forth. My question is, when do I train in the weight room to complement my cycling schedule? People always talk about the "off season" but I don't know when that is. I'm in California and there really is no time when its unpleasant to ride ... so when do I work in the weights when I'm on the bike too?

If it matters, I currently ride for 1 - 1.5 hours just about every morning before work (mostly hilly, 3-6 percent stuff, since that's what's around my home) and then try for between 30-60 miles, usually on Saturday.

Any suggestions?
