Here are few ways to market yourself:
-Visit senior independent/assisted living centers (if you want to work with seniors)
-Donate some of your services at a fundraising event
-Connect with as many doctors, chiropractors and other health professionals around the area you wish to operate
-Give free sessions to members at the gym you work at
-Acquire more certifications if you have the ability to do so in order to upgrade your services and profile
-Stay active through the IDEA fitness connect so potential clients can find you
I hope this helps.
