Also, there are the Spinervals DVDs or VHSs and Chris Carmichael has a video series to do while you're riding the trainer, too. I've only done one Spinervals, but it did help me a lot when I was doing it regularly. I'd like to get some others to work on.

By the way, the Spinervals that I do is the Uphill Grind and it helps with your hill climbing.
