My advice is that you explore classes in Bozeman, but don't assume that if you don't like one class you won't like another. Within Bozeman, you can find different levels of the same type of yoga and very different approaches to yoga.
In my opinion, the most important
guideline in looking for a class is that you should feel good when you
leave the class. If you find that a class is too easy or too difficult,
ask the teacher to recommend a class with a little more or a little less
challenge. If, at the end of class, you feel that something is wrong in
your body, tell the teacher. There will be a compensating pose you can
do to relieve your ache, spasm or discomfort.
