I have one more week of my X Train 90 day rotation and then I'm going to start this. I went on a power buying spree of all the videos used in this rotation so I can't wait to start using them! Only one I'm missing is Imax2, but I think I'll sub LowMax for that one because Collage characterizes the step choreography as "complex" yikes!! Also this rotation seems cardio heavy, so I'm sure the fat burning potential is enormous!
