looking at your profile, you have not been a trainer for a long time. While client referrals are a great source for trainers, that does not help when you do not have a client. However, you are working at a gym which probably has personal training.
Giving new member orientations is a way of demonstrating to a new member that you know what you are doing and the potential value as a trainer. I saw that you are about to get certified in yoga, and this is something that lends itself to a class setting where you will have more exposure than just working on the exercise floor.
I saw that you have Linked-in as an additional profile. I would suggest that you create a website where you can provide more information about yourself and what you do.
I get some business from my profile here on IDEAfit. Most of my business comes from referrals. My business is exactly the size I need it to be right now so I do very little marketing to new clients. When I am seeking leads for new clients, I still have the most success through my network, by asking existing clients to suggest me to others.
