The Spinervals DVD's typically cost $29.95 - you can try preview all the workouts online at www.mypypeline.com/coachtroy. The website has a coupon for one free workout. You can rent videos for as low as $1.75 and own them for $7.49. I'd suggest starting with Iron Girl 1.0 - Spinervals with IronGirl which has three, 30 minute indoor cycling workouts (easy, medium, and hard). There's a coach's note video that accompanies this (free).

Coach Troy gave an all day class followed by a spin session for my local triathlon club and he is the best.

In Australia/New Zealand the website is www.spinervals.au
