If you are a new trainer, I would recommend www.TheSixFigureTrainer.com with Stu. I found the site extremely helpful.
I actually took the e-class Stu does and it really helped me get started. One cool thing I learned was how to use 2 different maps to find high-end gyms in my area to work at and how to get an interview and get hired. Stu was really helpful and super nice. If you have a question, just email him and he’ll get back to you pretty fast.
