I got this dvd for Christmas nd I must say I LOVE IT! I think you will find all 3 workouts on it are fun. For me the time flies when I do one of these workouts.
It's amazing how mixing up the familiar IS workouts into the Terminator workouts makes them fresh and a brand new challenge. You will not regret adding this to your collection. Great for those days when you want to go FULL TILT!!!}(
It's worth it if you really like circuits. I love this DVD. I mostly use the Gauntlet and the Viper, but IMAX extreme is nice when you want an extra long cardio (I always skip the C&W compound exercises on this one).
