can you recommend a good beginners tape or DVD that I could check into? I have been thinking about yoga before, but I am afraid I will turn into a Pretzel.
I like Gaim's Beginner yoga series. I prefer the ivengyar (spelling) variety, which is more about stretching and relaxing than the muscle-building "power yoga" tapes.
I've found that it really helps my local back. Some of the poses are absolutely heavenly stretches for the back (especially Cat, where you get down on all fours and slowly arch your back up). Ones that might hurt your back can be modified to stretch it instead. Definitely don't go the power-yoga route -- you may want to get some props such as blocks and towels to help you position without hurting your back. The Gaim beginner video covers using props correctly.
Can you recommend any tapes that i could buy for absolute beginners? To me Yoga is still turning into a pretzel and sadly I am not that flexible anymore.
Actually you could try a search at your local library and get a couple for free to start. I took a few classes so I'm not sure on the best video people.
