You might be interested in a class where you can get in shape while learning self defense. Maybe you haven't decided on a style or location yet. Maybe you'll fall in love with this one. There's no need to commit to lessons and tuition without trying the class and getting to know the instructor. Of course if someone likes the class and insists on paying, a person could make a donation. One of the things you're really going to love about the Ball and Tiger style taught by Austin Area Shugendo Lifeways is that you don't need to be in shape to start learning self defense skills.
