If you have ever heard of the term ‘Polarized Training’ or ‘80/20’, you have Stephen Seiler to thank. Stephen is sought after by elite athletes and recreational athletes alike for his council on training design and structure. He fostered the concept of polarized training through his research as well as practice with elite athletes and is one of the foremost thought leaders in training research today. Stephen on Twitter- @StephenSeilerStephen’s TED talk- https://www.ted.com/talks/stephen_seiler_how_normal_people_can_train_like_the_worlds_best_edurance_athletesInformation on coaching: www.trainright.comKoop’s Social Media:Twitter/Instagram- @jasonkoop
