I gather from your reply that you are currently working at a gym and are not planning to strike out on your own (yet).
Remember that every interaction you have with another person at the gym is also observed by others. Let’s say you give somebody an orientation as many new trainers do for new members. Checking your email or text messages may be seen by another person even if the person you are training is not aware of it. Members in clubs talk to one another A LOT.
It may also be a good idea to strike up a good relationship with group fitness instructors who are often trusted sources for gym members. and their recommendations carry a lot of weight. Take their classes if you can. I hate to say it but men are a rarity in a group fitness class, and it will score some brownie points.
