Bob,
I should have mentioned that the only "problem" with yoga for men is that, at least in our area, most of the participants seem to be women. Rick was kind of intimidated about going to a class at first because of the female factor, so I went with him to the first couple of classes until he felt comfortable.

In the beginning he was absolutely sure that he would not be able to do any of the yoga positions, but he was encouraged by a book he read about it that said it is not as important to be able to actually DO them as to be TRYING to do them and trying in the correct way.

You might want to look for a class that has a male instructor.
