For one thing, it's not Tai Chi in any recognizable form. What it is, is a slow, repetitive series of moves derived from the traditional series of Tai Chi moves. I didn't find it to be of any muscular or cardio benefit at all. If you want to meditate, then buy something of that nature, because this doesn't fulfill that criteria, either. Plus, the DVD warns you that it isn't up to par for surround sound and so should rely on TV audio instead. Since this wasn't an inexpensive DVD it seemed that they overly skimped on the production quality despite the premium pricing.Save your money and buy a different DVD.
