I don't know how your gym is managed. Is the personal trainer also in charge of the tour in shifts, or is he in charge of the aerobic class? You can communicate with students more when traveling and during aerobic courses (such as spinning) to understand their needs and show your value. I think there will be students soon.

I have been in the gym for three years, and that's how I got my personal education. I'll get familiar with it first, and even become friends, and then everything can start.
