Twelve basic yoga postures are presented here in non-intimidating language. Ivanhoe calmly goes over the fundamentals of each posture as well as the importance of breathing. Anyone who thinks that they need to be initiated into a secret philosophical organization before they can do their first yoga posture will be relieved by this video.
Throughout, a narrator makes points about common misconceptions, "Bewares" (or common mistakes) and helpful tips and tricks.
The big downside to this tape is that it takes quite some time to get through the twelve postures (just a little over 45 minutes). While most absolute beginners would do well to spend that much time listening to all of the tips on alignment and breathing, slightly more advanced beginners (e.g., they've read a book or even gone to a class) may not derive as much benefit. Even the brand new beginner will probably outgrow this tape sooner rather than later.
Having said that, Ivanhoe is a very good instructor on this video, balancing calm and humor. Again, no one will be intimidated by her approach.
