Do a really awesome job with whatever members you have. Offer free sessions to friends and family if you need bodies in there. Getting referrals from the people you are already helping meet goals is the best advertising out there. Make sure the service your offering and the results your getting are high quality and people will come flocking in. Our gym never did any advertising, but focused on keeping the trainers educated, making sure we all knew all the members by name and created a family like environment. To this day, it’s the longest standing and most successful personal training studio in the city it’s in.
Aside from that, know what you’re good at and what clientele you want to serve. Learn how to meet their needs using your skills. Too many gyms are trying to help everybody, rather than focus on the people who they are naturally good at helping. Each trainer has a unique set of talents, cultivate those and help each person bring in business that fits their unique leadership style and passions. Align the trainers with the populations they will fit best with and you’ll be on your way. Easier said than done, but it creates longevity and happy careers.
