WHAT IS Armour39™?
Armour39™ is the sports performance monitoring
system engineered to empower athletes. The system
captures and displays critical information athletes need
to discover their true potential.
Armour39™ is the first system that detects and
responds to every move athletes make – any direction,
any motion, any position. So every athlete—regardless
of sport or workout activity—has precise information
about their performance. Athletes can measure, track,
and analyze what matters most—in the moment and
over time—to improve. Armour39™ measures heart rate,
calorie burn, real-time intensity and WILLpower™, Under
Armour®’s unique measure that reflects overall workout
difficulty in a single score.
YOUR PERFORMANCE.
YOUR WILLPOWER™.
DISCOVERED.

HOW DOES Armour39™ WORK?
The Armour39™ chest strap, made from the same
comfortable, moisture-wicking material that Under
Armour® is famous for, collects athletes’ information
and transfers it to the Armour39 module in the strap.
The module automatically transmits this information in
real-time to a Bluetooth® Smart display device, the
Armour39™ mobile app or the Armour39™ watch.
The Armour39™ module is the first sensor designed to
store information, allowing athletes to work out with or
without the display device.

With Armour39™, athletes of all sports can measure,
track, and analyze the data that matters most. Armour39™
measures heart rate, calorie burn, real-time intensity and
WILLpower™, Under Armour®’s unique measure that
reflects overall workout difficulty in a single score.
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.
INTENSITY

7
IMPORTANT: Armour39™ is optimized by completion of the
Armour39™ Assessment workout. The Assessment captures an athlete’s
baseline data and informs all other Armour39™ measures, customizing the
system specifically to the athlete. A user should perform the Assessment
regularly, about once a month, to ensure the system takes into account an
athlete’s current specifications.
WILLPOWER™ The true measure of an athlete, it is a
single score that reflects overall workout
difficulty on a scale of 0.0-10.0. This
innovative measure combines a range
of dynamic inputs including workout
duration, body position, user profile, and
key heart rate measures like ventilatory
threshold and recovery into a proprietary
algorithm. With WILLpower™, athletes
can—for the first time—objectively
measure a hard day versus a light day,
to ensure they are training effectively to
meet their goals.
