The title just about says it all. Not that pushups, burpees and punches aren't great exercises, but do you really need to buy a DVD to tell you "Do 30 seconds of X. Now do 30 seconds of Y."There doesn't seem to be much thought given to the sequencing or timing of the intervals, and there is little to no actual technique instruction. Plus, the three workouts follow a goofy upper body, lower body, whole body split, which is presumably borrowed from body building, but makes no sense in martial arts training where movements are not designed to isolate muscle groups.Hackleman's second home work out DVD "Crosspit" fixes many of these shortcomings and is a much better product.
