Really David? Bikram Choudury is currently involved in a stack of lawsuits. He's trying to sue anyone doing a similar style to that which he 'copyrighted' in order to make money. He is an ex-weightlifter, once a yoga champion at age 13, who popularized the notion of competitive yoga! Instead of a proper warm-up routine to engage the body and mind, the room is heated to 40C! It is a rigid, unbending routine of 26 asanas.
I've studied/practiced and taught yoga for 15 years. It is a love of mine.
Never have I seen such a rigid set of movements ruthlessly applied to all students. Yoga is a flexible art form at it's worst. It involves correction of postures, alteration of movements to suit the practitioner, and above all a tailored approach to those who are not in perfect health. It is the McDonalds of yoga because it is the 'fast food' approach - repeatable, and quick, with no real substance.
Yes, it may be suitable for some, as a type of aerobic stretching routine, but it should not be considered Yoga - which as you know means "union with the universal spirit". I agree that many western yoga forms have their shortcomings, but that doesn't make this style any better. Promoting it's use for people with I.B.D. is quite abhorrent.
