My BF has a Johnny G Spinner bike that he got last winter, and he has told me I can use it this year if I would like to. I have a Nordic Track Elite X-c ski machine, which I have had for 10 years, and have used it consistently 2 to 3 times per week, but would like to mix in some indoor cycling workouts.

I have looked at the Spinervals DVDs, and was wondering if anyone who uses them would recommend 1 or 2 titles for a beginner to start out with? Have to say, some of the titles are a little intimidating!

Also, as far as the CycloCore series, can these be used with a spinning bike, or a trainer only?
