Basically I'm a cardio addict, I love the high. My current regime is: I alternate cardio with a total body workout dvd. That's all good but I've found out that with my body type, I tend to bulk up easily - I'm only 5" but curvy, I weigh about a 110. I was wondering about the toning benefits of yoga, I know Jen Aniston had been doing it and her body looks awesome now, so lean and toned. For those of you who do it, do you find that it tones and firms you? I bought 2 dvds, the Kristin McGee power yoga one and the Sara Ivanhoe one, and plan to alternate them each morning and do my usual treadmill on other days. So my q is, does it really firm and tone? I'm wondering how stretching can help you..... What are the benefits of yoga and would you recommend it?
