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.

Can Do For You

Many coaches and trainers I have spoken to feel that Periodization is too time consuming, too complex, too rigid and does not work for my athletes/clients

Those comments are based on a misunderstanding of what periodization REALLY IS.
