Raise awareness, for example:
1. Play the competition video of bodybuilding coach.
2. Fitness knowledge lecture hall.
3. Online experience exchange of bodybuilding coaches. (This is of interest to everyone.)
4. Lecture on slimming methods.
Solicit business, such as:
5. Discount card. Download the cash at the bottom of the discount card.
6. Couple card.
7. Couple card.
8. Family card.
9. Friend card.
You said that you are networking, so networking should mainly provide a means, way or way of publicity. It's all a matter of planning.
Be careful if the gym owner asks you to practice planning. Pay attention to communicate with the gym owner when planning, so as not to be dissatisfied with the boss after the activity.
I wish you success!
