getting the first client is always a tough one. However, I see that you are a fitness instructor and teach classes. This should give you some exposure to potential clients. I looked at your profile and saw that you teach Turbo Kick.
However, you list as specialties that you are also a yoga and Pilates instructor and an athletic trainer. Those are substantial credentials, and you should make the most of them. I believe that yoga and Pilates are much better taught in a very small group, and they have the added benefit that they require very little equipment.
Have you considered offering small group instruction in somebody’s home? It may not be that much per person and is thereby not such an investment for the clients but you can begin to build your resume. And one of them may have the desire to train with you individually.
From what I read through your answers, it appears to me that you enjoy lifting heavy weights and high-intensity activity. Good for you! But: this is not necessarily the ambition of the paying clientele. Clients want to identify with you as a trainer.
