Connections.....If the new gym owner was a tumbling coach for a local high school, ymca center, rec center, etc. then people feel comfortable following the coach and making the transition from that place to the new local gym for tumbling and eventually possibly all star teams. Additionally, if there is an unmet market (such as no gym being within 30 minutes of a high school/community,etc.) then people will try out the gym because it is close (especially if there is a free trial class). Many parents of sideline cheerleaders aren't willing to drive very far to put their kid in tumbling classes, so it's a good way to start getting students. After that base, through good reputation and word of mouth the program will build.
