I have done the same. "Lifted" some exercises that seem to work for me. In one sense the exercises can seem a bit different and difficult, so I can understand that some people work as instructors in it. On the other hand, the great thing is that they mostly are different than your regular stretches and so forth, so it is a inspiring supplement to more conventional exercises.
