Training programs on DVD/CD - from fitness level to hard core Ironman and pro racers!. The most efficient way of beating the traffic & darkness - and getting ready for a strong race season. ALL titles feature gearing ratio changes (front chain rings & rear cassette settings) and can be used with "turbo" trainers (such as Elite, CycleOps, Tacx, Spinervals, etc.). If you are using a spinning bike (such as LeMond Revmaster) or stationary training bike then, for best results, we recommend using Fitness 3.0, 4.0, and Competition 10.0 - 19.0. In addition to settings for "turbo" trainers (gearing ratio changes), these titles include a 'tension' graphic for stationary and spinning bikes.
