Great profile
I suggest getting involved in your community
Join the Chamber of Commerce
Offer group fitness at a local gym, you may get one on one clients from that.
Start an outdoor bootcamp, again, great exposure and you may get one on one clients
Wear a T Shirt with your logo on it
Put a magnet on your car with your business info on it
Ask your local paper to write a fitness column
Do you have a website? If not create one
Participate in Health Fairs
Put your cards/flyers everywhere
Offer your current clients some type of reward for referrels
