Query: surprisingly great workout

I have never written a product review before nor have I ever watched an exercise DVD by this woman before. I am an ACE personal trainer, a certified yoga instructor, a classically trained and certified Pilate's instructor as well as a board certified neuromuscular therapist. Most exercise DVD's leave me cold as they don't have the proper form or are just too ridiculous. This DVD is a total exception. I was IMPRESSED!! This video kicked my butt and the butt of a few of my 20-something students. I bought the box set that has this DVD plus the fat booster plus the trouble spot. An EXCELLENT purchase. Get these three dvd's plus Brooke Siler's Beginning Pilate's for weight loss and Shivea Rea's Creative Core yoga dvd and you are set for months!
