Training Stress Scores (TSS) User Guide

With Training Stress Score(TSS) you can find out just how hard your workout really was and track your fitness over time with the Performance Management Chart (PMC).

Based on the gold-standard analysis system that has been available on our advanced WKO+ desktop software for half a decade, online workout scores can be calculated based on power, heart rate, and more, allowing athletes to earn a score for a variety of different workouts and compare many different types of training.

Scores can even be calculated based on data that you already have recorded in your account: click here to learn how to use our back-fill calculator tool to instantly update your charts with all your past data, and make sure you have set your threshold values correctly to ensure accurate scores.
