What does it take to
stay exceptional for decades?

Entropy measures how hard your body is working to shed heat, read from your temple.

At rest, it shows the load your body is carrying across many systems: thermal, immune, digestive, cognitive, emotional, pharmacological, postural, reproductive, and recovery. Healthier bodies maintain low Entropy at rest, and we call that your Baseline.

During activity, heat dissipation becomes mostly aerobic. The highest Entropy you sustain near your max heart rate, is your Threshold.

Your Baseline and your Threshold combine into Momentum: the one number that shows you how well your body is doing across a wide range of systems.
