Built under load.

The most capable version of you at 40, 50 and 60 is built under load. HEAVY measures every ruck — distance, climb, heart rate and the weight on your back — then tells you exactly what to carry tomorrow.

Bounded by a safety envelope built from your own training history. Never a number it didn't measure.
