This is a hard one to answer. I just did IMAX 3 this morning after many months of not doing it. I burned over 500 calories. With MIC, I usually just do the hi/lo portion which is the most intense part of the workout for me (I don't care for the step portion). The recovery periods in IMAX 3 are definitely not long enough for me. I guess I have to take MIC out again and see how I do with it. It used to be my most dreaded cardio workout. With IMAX 3 this morning, I was finally able to do intervals 1, 4 and 7 the whole way through. Why not do a mish-mosh of MIC hi/lo and the IMAX 3 blast only premix (24 mins.) or step only premix (31 mins.)?
