I LOVE the two cardio workouts on HC Extreme. I haven't done the other workout. Before I got sick these cardio workouts were getting used a lot...now I will be back to square one if I ever get better.

P.S. I would still buy Imax 3 eventually. It is a great workout as is and I enjoy the premixes: 1-5, 6-10, step only, blast only.
