I train all my runners and jumpers with the Flexible Periodization Method and their PRs just keep coming. The individual programs help them a lot and the best of my athletes are breaking into the top ten in their events in Sweden. I coach track and
field in a multisport club and we are now working on integrating the FPM in the
other sports, cross-country skiing, bike racing, racewalking and orienteering.

Do you offer CEC/CEU? 

 Flexible Periodization Method Specialists hold personal training and strength and conditioning distinctions through a multitude of organizations. As such, FPM courses fees allow room for you to petition your certifying organization. 

How do I maintain my distinction? 

Maintain your basic personal trainer or strength and conditioning certification (NSCA, ACSM, CPTN, etc.). There are no ongoing FPM CEC/CEU requirements. Your FPM distinction is valid as long as your basic certification is valid.

Periodization is too complicated, too time consuming, and may not work for my athletes. Is that true? 

We address common misconceptions about Periodization in this article. 

How do I get the most out of the FPM programs? 

When you register for an FPM course, you get complimentary email access to Karsten, the creator of The Flexible Periodization Method. This is an opportunity for you to ask pointed questions about the course material.
