WHAT DOES Armour39™ MEASURE?
HEART RATE
A highly responsive, precise
measurement of heart beats per minute.
CALORIES
An advanced algorithm that captures
calories burned with a high degree of
accuracy. It takes into account nuances
like changes in heart rate and body
position that impact how hard your body
is working.
This real-time measurement captures how
hard an athlete is working by measuring
current heart rate as a percentage of the
athlete’s max heart rate. It’s proof of how
hard you’re working relative to your peak
ability.
