If you've never done yoga you're probably thinking, "What? I could do that pose any day!". But there are so many steps to get to this pose that by the time you get there it feels real good. And you feel like a strong warrior! (Okay, I'm getting really into it).
I am the most inflexible woman on this planet. I couldn't even bend over and touch my toes. I was practically touching my knees. But after 6 weeks of yoga I can touch my toes, and I have toned arms too.
