I have had my own business as a personal trainer for over 10 years. I absolutely love what I am doing; it does not even feel like work. At this point, I am well-established. Getting started is another story. It’s not easy to get your first few clients. You may need to start training friends for free or for a small fee just to be visible. Working at a gym was part of my start as it gives exposure. I used to work in a large gym before I decided to go off on my own.
Overall, I really enjoy being off on my own.
