There is definitely a ton of yoga that doesn't concern itself much with woo, but it can be hard knowing whether or not you might run into some going in. And from what you're saying it does sound like it's not for you.

Went and got YAYOG to see what you were talking about (since I'm trying to get back into an exercise kick myself right now) and yeah, there is waaaaaay more male power fantasy stuff in the text than in the Body By You book. Additionally, I think the Body By You book has a more straightforward program of exercise progressions, even though YAYOG has more exercises listed, and I think the range of the exercises starts easier.

I also really like the way the BBY book has your initial assessment of what level of exercises you should start out with as well as not having a defined progression of what level of exercise you should be doing week by week--you move up the ladder when you can do the full set with good form. So, my advice is to try and find the BBY book--it's probably the least odiously burdened material you're seeking. If you feel like you're graduating out of BBY or getting bored with the exercise on rails, hop on over to the YAYOG book instead.
