I usually do my cardio early morning before I go to work. I would love an extra long, extra intense step video, perhaps broken down into 3 parts, that I could choose to do either in one day or break up through the week (depending, of course, upon what time I actually wake up). Something along the lines of Step Blast, which is without a doubt my favorite Cathe video. I do all my lifting & ab work in the gym, but I depend on Cathe for my cardio during the week. If I had my choice Cathe would do cardio only videos from here on out.
