Um... no... Yoga is anything
but new age hockum - that is a very rude and ignorant thing to say. Before you berate it, I suggest you try it as well as do some research. I've been taking yoga for three years now, and have
never been exposed to any "semi-mystical nonsense". I do own a mat - because I prefer to use my own, instead of using the worn-out mats at YMCA. Also, because my knees hurt, my mat is a tiny bit thicker, reducing the pain and allowing to make my yoga practice more productive. My yoga instructor is a former competitive athlete, a marathon runner, who was directed to yoga by her cardiologist to help alleviate a rare heart condition she had. She is now in amazing health, she no longer has to take medication for her heart (initially, the condition was believed to be of the kind to require medication for the rest of her life), and does mountain biking on weekends for fun.
Here is American Heart Association's scoop on yoga:
Yoga and Heart Health. There are also numerous articles by orthopedic surgeons who routinely recommend yoga to people recovering from serious injuries and surgeries. Do you honestly think cardiologists and orthopeds - scientists who spent many years studying everything there is to know about how human body functions - would recommend what you call "new age hockum"?
Yoga is hard work and can be tremendously beneficial. It's not uncommon for me to sweat as much in my yoga classes as I do in high-intensity cardio. And the amount of muscle building is comparable to that of a decent weight-lifting session. The class I normally attend includes gymnasts, professional dancers, weight lifters, and at least one football player. Many folks in the group joined just to try it and made it a part of their fitness routine. And many were directed to yoga by their doctors and coaches.
