That will ultimately be your call… But, if you are looking to do a self defense class, one idea would be to teach that separately to women. Then, you could offer a mixed Bootcamp where men and women could benefit. Two different classes–two different approaches. This may attract some women who are interested in the self defense class, but not necessarily the Bootcamp.
Another idea is to do a mixed bootcamp class as you mentioned, but incorporate self defense moves into it. I would probably keep it mixed male/female as they could both benefit.
So, you have different options, but you could always market/ask around to see who is interested before you decide. Sounds like a great class, though!
Good luck to you.
