WHAT DOES STEPHEN SEILER SAY?

STEPHEN SEILER

Exercise physiologist, polarised training pioneer

Coaching

Stephen Seiler's research helped turn endurance-training intensity distribution into a measurable question. His 2010 review described an approximate 80/20 pattern by sessions among high-volume competitive athletes, while later research shows both pyramidal and polarised distributions. Roadman uses that evidence with its denominator and population intact instead of presenting 80/20 as a universal law.

EXPLORE BY TOPIC

Where Seiler lands on the questions people ask most.

On Polarised Training

The 80/20 intensity split measured across elite endurance sport.

On Zone 2

Low-intensity aerobic riding — the foundation everything else is built on.

On Threshold Training

Training at and around lactate threshold — the dose that drives the biggest gains in trained riders.

On FTP

Functional Threshold Power — what it is, how to test it, and how to raise it.

On VO2 Max

VO2 max intervals — the high end of the engine and how to build it without burning out.

On Reverse Periodisation

Flipping the traditional model — building intensity early and volume later, and when it actually fits.
