When I bought this item I was looking for a tape that would reintroduce me to some of the basic yoga asanas and principles of practice. In particular, I wanted a tape that focused on fundamentals, that emphasized proper form and how the asanas should feel while you are doing them, and that included modifications for people like me who are flexibility challenged. Also, I did not want a tape that emphasized the "flow" from one pose to another, because some of the videos I've seen in that style either don't give enough instruction for my level or assume that the viewer has more experience than I do and needs less instruction on the basics. This tape is great for all of those things I wanted, and it has none of the features I wanted to avoid.
I have used this tape for maybe a dozen or so sessions, and I still learn a little something about doing the asanas every time I view it. I suspect that'd be the case for many more viewings to come.
The limited number of asanas demonstrated makes it easy for beginners, or those coming back to yoga after years away, to focus on getting them right. However, after several viewings, I imagine that many purchasers, like me, will want to branch out from the "daily dozen" poses. And, the slow pace of the tape and emphasis on detailed pre-pose instructions make it a little tedious to follow after a while. But, those are not really criticisms per se, because no one tape could possibly fulfil the needs of everyone every time. The tape does what it purports to do, and does it very well. Besides, once you know what's coming, it's easy to simply get into the asanas earlier, hold them longer, etc. The instructor is charming, and she knows her stuff, which counts for a lot when it comes to viewing longevity.
I will soon purchase other tapes to expand my yoga horizons, but I suspect I will return to this one periodically for a tune-up and change of pace. It's worth keeping in the collection.
