TEI
TOTAL EFFECT INDEX.
Measure what matters.
A training workload intelligence system that helps you value, compare, interpret, review, and plan your training experience and its accumulated effect over time.
WHY TEI
More than a number.
A clearer picture.
TEI helps you make sense of your training by capturing the key variables that influence effort and effect. It turns individual sessions into meaningful insight — so you can see the bigger picture and make better decisions over time.

Understand the workload of your training experience.
COMPARE
See how different workouts, days, or training phases relate to each other.
INTERPRET
Turn data into meaningful insight, not just isolated numbers.
PLAN
Use what you learn to make smarter training decisions over time.
