Congrats on opening your studio!
I concur with Susan…Have you done an official grand opening day or weekend yet?
If not organizing a grand opening is a lot of work but worth the effort. Some ideas are to get local radio stations involved (like Susan said), offer something free and immediately satisfying to bring people into your studio like smoothies or lemonade, get banners, and something fun for kids partake in like bouncy castles. Find other nearby businesses to exchange services and deals with to offer your potential members during the grand opening. Sign members up the “grand opening day” only special for significantly cheap prices like $9.99 membership/classes. Have them fill out something short to get their basic information like email and you can then later do email campaigns.
I have other marketing ideas for spring, summer, social media, and charity sponsorships for fitness studios or health clubs on my Gym Business Blog called Gym Insights. If you want more ideas, check it out at http://www.gyminsight.com/blog. I try to post something new every business day.
I hope this helps get your wheels turning and I wish you and your new business the best!
Best in Health,
