I did the High/Low Interval mix of Hardcore Extreme today - wow, is that tough! I don't have the HCE DVD, so I just switched LowMax and Imax 3 in and out. I needed those little breaks, let me tell you!! I didn't do the Kickmax Bootcamp drills, either, but I still got an hour's intense interval training. Whoowee! I've definitely earned my curry tonight. :7
