I had the time to do the whole thing today and it is just great. I have a variety of yoga DVD's and particularly like Eoinn's, Bryan's and Baron's practices. What I don't like about them, though, is that they talk nonstop - blah, blah, blah, blah, blah (particularly Bryan and Baron). It's okay the first time or two you do one, but it gets really old after a while. Even though Tony is generally a chatterbox, his comments are alignment-oriented and very helpful in this DVD. It's challenging enough for experienced yogis, but it's so well-cued that I think fit people who've never tried yoga would get more out of it than beginning yoga workouts which just don't provide a physical challenge, even if they do teach you about the poses. Tony's form isn't the greatest and he could place more emphasis on breathing, but aside from that, this one's really a winner. Doing the second half (beginning w/balancing postures and possibly skipping "yoga belly 7") is a great 25-min add-on.
