New Course Is the First Polarized Training Certification Offered by a U.S. Olympic Federation

April 2, 2024 – Colorado Springs, Colorado, USA – USA Triathlon, the Olympic governing body for the sport of triathlon in the United States, and Fast Talk Laboratories, experts on endurance sports training methods, have partnered to produce a Polarized Training Certification Course. The new Polarized Training Certification offers coaches a comprehensive education in the 80/20 training method explored by Dr. Stephen Seiler and is now available to all endurance coaches at

The polarized training method, sometimes called 80/20 training, has become increasingly popular thanks largely to groundbreaking research by Dr. Stephen Seiler at the University of Agder in Norway and his colleagues. While examining the practices of elite endurance athletes from a variety of endurance sports, Dr. Seiler’s research found that high-performing athletes were doing workouts that were either low intensity, extensive, and low “stress” or high intensity, focused, and “high stress”—a polarized approach. In this training method, athletes devote about 80% of their training sessions to lower intensity exercise and about 20% of sessions to higher intensity workouts, often through interval workouts. This practice became known as the polarized training method, or 80/20 training, and is practiced by many elite, age-group, and masters athletes in triathlon, cycling, running, cross-country skiing, and other endurance sports.

USA Triathlon’s new Polarized Training Certification course, produced by Fast Talk Laboratories and drawing heavily from contributions by Dr. Stephen Seiler, certifies that coaches have a comprehensive understanding of 80/20 training. The course reveals tangible tools coaches can put to use immediately in coaching and training athletes. This course offers a full exploration of polarized training including:

  • The principles and hallmarks of polarized training
  • Intensity distribution
  • Durability
  • The three-zone model
  • Polarized exercise physiology
  • Polarized workouts for swimming, cycling, and running
  • How to design and implement an 80/20 training plan for any endurance sport

“After seeing the success so many athletes have had using polarized training, coaches have been clamoring for more information on this method,” said Liana Tobin, USA Triathlon Education Manager. “Our collaboration with Fast Talk Laboratories enables us to offer coaches best-in-class coaching education on the hottest topics in triathlon.”

“It’s gratifying to see my research being applied both at the highest levels of sport and among age-group athletes,” commented Dr. Stephen Seiler. “The science shows that polarized training is a highly effective way to prepare for high performance, and I’m glad my contributions to the field have been formalized into an educational course for coaches.”

“The Polarized Training Certification course is the highest-quality educational content about this important and increasingly popular way of training,” said Trevor Connor, cycling coach and CEO of Fast Talk Laboratories. “Fast Talk Labs is pleased to help USA Triathlon show its continued commitment to coaches by investing in advanced, specialized coach education.”
