Could be my preferences, but this isn't the best of the YZ tapes I own. It seems to flow less well, the poses aren't held long enough, and though the instruction from Alan Finger is great (as always), I just always feel like I want more after doing it. I want to do sun salutations more than twice, for instance. For strength, the Power Yoga for Strength and Endurance is much better. For relaxation, Conditioning and Stress Release leaves this one in the dust. I'm a high-level beginner in yoga, and I only do this one occasionally, and only for the poses that aren't included in my more-favored tapes (cow's head, seated spinal twist).
