I bought this video to punish myself. It works. Some people complain that the video is too long but it breaks up challenging poses with isolated toning. The routines are easy to follow, I like the alternatives to the poses that are always on display. Weightlifting with yoga has a calming affect although it's not as spiritual as just yoga. My only issue is the presentation of Anthony Carill but that's just me being picky - I don't like the soft speaking. The poses combined with the weights will always challenge you, just add more weights and take the poses deeper. One day I want to be able to do this on my Bosu ball. With the balancing challenges I noticed improvements immediately. Every time you do the video you improve and that is very motivational.
