My experience with fitness mentors was not a good one, unfortunately. I found it very frustrating that a lot of the information on the practice exams kept marking my answers as incorrect, but when I looked in my NASM book, I was actually correct. Fitness mentors also doesn’t explain things very well in the audio section of the study guide. Someone is simply just reading the text to you, instead of having a helpful lecture of breaking down the material. I can read the book myself. Anyway, it was a waste of money for me. I don’t recommend it. I’m glad others have found it more helpful.
