How can I spread information about my gym and personal training services offered in downtown St. Louis?

I own a health club in downtown St. Louis and I'm the personal trainer there. I'm having the hardest time trying to spread information about our facility to the downtown businesses and residents. Nobody likes it when you cold call, building security won't let you by the front desk, and most people park in lots that are secured and no flyers are allowed. I'm not trying to hardsell people, I just want to have our information in their hands, thats all.How can I spread information about my gym and personal training services offered in downtown St. Louis?Riverfront Times advertising. Advertisements inside downtown restaurant restrooms. Advertisements in buses with routes from nice suburbs to downtown and in Metrolink trains. Coupons distributed through the downtown grocery stores, dry cleaners, and other vendors. Web site and Facebook page. Rewards to current customers for people they refer to you.
