"Superb and honestly worth ten times the price. I can't think of a better form of continued professional development. Quite honestly I can say that this was the best learning experience of my entire life. [...] The course has a fluid informal feel, whilst encouraging everyone to interact and benefit from each other's questions and experiences. Menno is rare in that he interprets, implements and teaches a completely rational, evidence-based approach but with clear creativity and flair."

The 7-month curriculum

The testimonials speak for themselves.

The Bayesian PT course has helped me to better align my coaching practice with the latest evidence in nutrition and training. The quality of education rivals and even exceeds that found in upper level university courses. It should be the standard by which all other PT courses are measured.

Brianna Neuwirth, Registered Nurse and Head Nutrition Coach of Neulinea LTD

The Bayesian PT course has been the most valuable investment of my time in my career as a personal trainer. I have seen exceptional results having applied the diet and training principles to my client base. I highly recommend this course to any trainer dealing with clients who are interested in losing fat and gaining muscle.

Richard Kerr-Phillips, Personal trainer, fitness model

How many of us have fallen into the trap of bro-science and follow the wrong advice ...and how many times? It took me a while to finally find the people I can really trust in this field (but I will always doubt): Bret Contreras, Brad Schoenfeld, Alan Aragon, Stu Phillips and, of course, Menno Henselmans. [...]

I decided to follow his last advanced PT course. I was not disappointed. Even though the course was imparted online via Facebook, this was not an impairment and we had constant feedback to the various topics discussed and detailed replies to the questions posed by the participants. I definitely learnt a lot and that is why I will not hesitate to enroll next time Menno gives his regular PT course. He is definitely worth it.

Isaac Perez Castillo, PhD graduate

Menno Henselmans has put together one of the best courses I have ever been through and I could fearlessly recommend his work to coaches anywhere. If you’re looking for a place to learn legitimate and thorough information on both training and nutrition that is filtered in a way that you can directly apply to your clientele, check out the Bayesian Bodybuilding certification. It’s the real deal.

Frequently Asked Questions (FAQ)

  • q-iconDo I have to be present at specific times?

    No, all materials can be downloaded and studied at your own convenience, including live sessions and the physical meet-up. We have students from all over the world.

  • q-iconI'm going on vacation during the course period. Can I still follow the course?

    Sure, many people have a holiday sometime during the course. You can follow the course at your own pace. That said, most people have found that they benefit from keeping up with the group. In principle, it’s exactly like following a part-time online college degree.

  • q-iconHow intensive is the course?

    The course is designed to be part-time, so you can follow it alongside your work or studies, but it will require a serious time commitment, such as in the evenings or in the weekends.

    At a minimum you want to have one free evening per week and several days before the exam to follow the course. (Unless you’re not interested in the certification. Then you can of course work through everything at your own pace.)

    If you don’t get around to studying all the materials before the exam, you can postpone the exam to the next course round.

  • q-iconDo I need to have any minimum education level before I can join the course?

    No, the course covers every topic from level A to Z. Of course, if you don’t know what carbohydrates or exercise repetitions are, you’ll have to invest more time to learn everything than others.

  • q-iconCould you tell me more about the exam?

    It’s an open-book exam that takes place via online software also used by Yale University. The Latin Honors system is used for grading and this will be printed on your hard-copy certificate. The pass rate is ~97%. There are no resits, just like in life: you get one exam per course registration. You can, however, postpone the exam indefinitely to a future round of the course.

  • q-iconDo I have to be a fitness professional to join the course?

    No, many non-professionals have already followed the course simply for the sake of self-improvement and their personal education. You don’t even have to take the exam if you don’t care about becoming certified.
