I certified PN1 last year and at the first of the year ran a Buddy Boot Camp which included a strong nutrition component. By doing so I was able to charge more than I would have for a workout only camp. We had a private FB Group where the nutrition portion was conducted. All the feedback I received was positive! No regrets for spending the money for the course!!
PN is great! It does a great job of breaking down the information for you to learn and then teaches you how to inform your clients. It teaches clients habit based steps to improve or attain a healthy lifestyle.
The FB group is great as it gives all coaches an opportunity to learn and grow from each other. I highly recommend the cert!
