I think Yoga is great & all, but the concrete knowledge of actual muscles and how they are laid out is invaluable and has increased my understanding immensely. Yoga is kind of like a phenomenal 'Best Guess" made 6000 years ago by people who didn't necessarily know what they were working with. Now I can know specifically what muscle is sore, and how it works mechanically so isolating a stretch is easier.
Yoga's contribution is breathing and meditation. Yoga literally means "the expansion of consciousness by directed meditation." The physical aspect is simply stretching. The bottom line is that, until physicians vivisected the human body, the communicable reality of muscular mechanics is vague.
How bizarre it seems to me that we have classes in primary school that we make children attend where they jump through hoops all day but learn absolutely zero about anatomy & physiology. Yogic meditation and poses work, but without the underlying theory, the physical sensations of hyperextension and hyperflexion, for example, can't be understood. People do hurt themselves stretching. Yoga is not like sports medicine. Sports medicine includes a constant awareness of limits and technique. Yoga is presented as a spiritual discipline without a rationale for its physical component, or at best, a conceptual, imaginative rationale- which does lower the bar for entry as opposed to the deceptively complex nature of scientific explanation. That said, scientific understanding combined with Yogic practice closes those gaps in practice and the benefits of practice are boosted even further. I always felt, with Yoga, after a certain point, you hit a wall of diminishing returns. Scientific understanding IS the doorway in the wall leading to greater returns, not more and more complicated and complex pretzelized asanas, which, without some sort of concrete conceptual basis are an open-door invite for stretching injuries. If Yoga causes or has caused discomfort or injury, scientific knowledge of anatomy will go far in explaining the causes and cures by illuminating limits.
Some Yoga poses, I think, are aggressively beyond the capability of most people. The benefit of my experience for newbies is this: learn the theory of movement through anatomy, and experience the Yogic practice with this in mind. Injury seems inevitable if you adopt the transcendentalist mentality that your mind is everything, and your body's limitations just a roadblock to be ignored and blown past. Some forms, Bikram "Hot Yoga" in particular, favor this kind of belligerent, fast-forward mind-over-body approach, and I caution newbies to be aware of this. Bikram's own philosophy is absolutist. And one should never trust anyone who owns more than 20 Rolls Royces and claims his brand of Yoga is the "McDonalds" of Yoga, and makes arguments appealing to traditional knowledge, like that his (copyright) series and poses are the "true and correct" ones and one should not deviate from the practice because it is 4000 years old and was written in sanskrit by uber-Yogis who had acheived dizzying hieghts of expanded consciousness.
One doesn't need Yoga to stretch. But stretching does gain an essential mental component from Yoga. The east-west sythesis of both opens up new possibilities for both and opens a pathway toward greater understanding.
