For me, Cycle Max is still a challenge, though I do go the distance. Toward the latter part of the workout, I am unable to stand for the entire time that the crew is standing. Perhaps I have my bike tension up higher than they do? Probably not! LOL. I was looking at Mindy's cycling DVDs on Amazon, but didn't purchase b/c I wasn't sure if they'd be challenging enough. Glad to read that someone here does find her workouts to be worthwhile. I purchased other cycling DVDs prior to Cathe's DVD coming out, so that I would be ready for her. I bought a few cycling DVD series that are virtual outdoor rides. I do enjoy them, but haven't done them since getting Cathe's Cycle Max. As for calorie counts in the WM, I've been using the formula suggested (body weight divided by 2.2 x MET value x length of time of workout) and have found this calculation to be rather accurate in calculating calories burned.
