Oh, that can very so much. Location, experience, track record, greed, market demands, specialties, and the list grows every day. When I first started I made around $8000/yr so don’t expect instant stardom. Concentrate on providing a valuable service and always have an exit strategy, this business can have a high turn-over rate. If you can prove your worth, you’ll thrive but it may take years. No one thing makes a great trainer, its their journey to get there that will ultimately define them.
