A good place to open one is where a lot of human "traffic" is going to be flowing. One of our dojos is located adjacent to a mall, so people who want to know more about the arts will more likely stop in when passing as opposed to getting off the couch to go check one out. We are open from 9 am to 9 pm Mon-Fri and 9-2 on Saturday. It also helps if you can start a Cardio type program to bring in more customers, other than martial artists, to help spread the word.
