Hi Sacred,

You might want to give a yoga class a try. I found the tapes to be a bit difficult to follow, especially when you're having troubles getting into positions. If you can find a good class to attend, the teacher should be able to show you modifications that are appropriate for your skill/experience level.

Another option is to get "yoga conditioning for weight loss" on DVD (if you have a DVD player) as there are 4 different difficulty levels, allowing one to get the proper alignment and the benefits of the posture without having to be gumby
