I never contemplated Yoga though..I guess it was the stereotypical image I had it was only for Volvo-driving housewives.

Kind regards,

LMAO! See! That's more or less the same image I had of it too. That or a really wacked out new age type person doing it. And it's really not the case! Just think of it as stretching.
I didn't really think about taking it up. I was in our local Half Price Books and decided to look at the workout videos. Actually I was looking for a video on Tai Chi. And this video that I picked up, was dirt cheap, and I thought, well, it's only $6.00, what the hell I'll give it a try. So, I went home and watch it, like most workout videos recommend the first time around. And I thought, this doesn't look too hard! HA! Like Bobby said, some of those positions are not easy to hold for a period of time. Especially when you are working muscles that don't get a lot of work all the time, or if you sit for long periods of time. Or if your coordination is a little off.
