First off:
This DVD is not, I repeat, not for anyone that has any real Tai Chi practice under their belt. I have had very limited instruction, and I was disappointed with the Tai Chi form presented as the "third" exercise of this disk. My most rudimentary Tai Chi DVD presented a better form in the first 5 minutes.
But, having said that, there is one overriding feature of this DVD that makes it a must buy for anyone wanting to incorporate some Tai Chi and Qi Gong elements into their daily fitness routine. (Or that has any interest in learning Tai Chi or Qi Gong) Matt Cohen teaches the entire routine in mirror image poses.
OK, what does that mean?
Watch most every other workout, or Tai Chi DVD. The overwhelming majority of the time as you perform the moves, you "mirror" the instructor in screen. That means when they say lift the right arm, you end up lifting the left arm because it is on the same side as the person in the screen. Matthew Cohen takes this very common and normal human behavior into account, showing the left leg forward, but saying right leg, etc... This makes it about a million times easier to follow the routine then I have ever experienced before. Absolutely zero eye muscle confusion based on what I was seeing on screen.
Another additional benefit, the first two sections of the Tai Chi exercise have in the short time I have owned this DVD, replaced my stretching and warm up routines. In a few short minutes, I feel like I am more then ready to take on any number of strenuous exercise in only about 5 minutes. That works for me, cannot speak for anyone else.
