Not for Beginners, or anyone else . Attempting difficult poses, even modified versions, is a sure-fire way to discourage beginners from the practice, or make them feel inadequate, which is not what Yoga should cultivate. Even as an intermediate yoga practicioner, I did not like this tape, primarily because it throws you into the difficult poses without first generating sufficient heat in the body. The warm-up poses are minimal, static, and do not prepare your body sufficiently for the extensions and compressions of the advanced postures that follow. Besides all that, the instruction goes from excrutiating detail to not enough information (you have to break concentration and look to see what's going on) in the course of a single series of poses. Very frustrating. As if that weren't bad enough, the instructor's amazing flexibility is about the only inspiring aspect of the tape; her monotone delivery and the spare studio setting with no students make for a no fun experience
Output:
NEG
