I took a peek at this when I first heard about it, and decided against it, simply because I already have the best kickbox tape, bar none, in the business, in Kick, Punch, and Crunch...with the different premixes and workout blender, I can pretty much do a different version of this each time.
When I want a form refresher, I have Kelli Roberts Kickboxing for Dummies, along with ACE's Guide to Kickboxing, which are both real good resources.
