Salsa, I'm new to Spinervals, but I just ordered a couple that I am liking so far.

One is the Tucson "Virtual Riding" DVD, with the main effort being an hour-twenty of tempo up the Mt. Lemmon climb. There are also a couple other loops on there, too. Since it is just a steady effort...even if you aren't up to an hour of tempo, you can do the tempo you want, and then just do the rest at an aerobic pace. I like the scenery, and I like his coaching tips regarding form, breathing, etc. And, it is kind of fun to see the scenery with the steady climb. It really does remind me why I'm doing this...I'm reminded of how the long climbs feel, and why I want to be doing tempo in my living room with my front wheel elevated.

Another one I got to save myself some money is an audio Spinerval. It is the high cadence interval audio CD. It is less expensive, and you can load it on your iPod and listen to your own CD music in the background. I am weak at spinning a high cadence for long periods, and this is a very doable workout that I feel sure is going to help me. In fact, has already helped me...I can tell.

And, for some other trainer info, especially if you are doing some climbing, checkout Arnie Baker's website and some of his e-books. (It Googles easily.) I bought his ACE (Altitude, Climbing, Endurance) book, and I have been very happy with it. He talks about trainer workouts in it and gives some ideas for one-leg intervals and other workouts. He also talks about the equivalencies he believes about trainer vs. climbing on the road...like how much trainer climbing equals how much road time, etc. And, I think he has some specific e-books about using the trainer for climbing training, with structured workouts included.

Enjoy your trainer!
