I have completed several fitness and nutrition certifications, and this one, by far, has been my favorite. The ease of use, the depth of information, and the wonderful support is unmatched. The interface is very user friendly, and the science-based lessons are interesting and useful. I have found it easy to integrate what I have learned into my own life, as well as, explain and utilize with my clients. The resource library is fantastic, and I have reached for many of the resources more than once. I am also a coaching client and have been feeling and seeing the benefits of this certification in real time. If you are on the fence, go for it! You will not regret it!
