You've never trained this way. Nobody has. Armour39 is the first-of-its-kind performance monitoring system. It literally tells you how hard you worked.

Armour39 is the first-of-its-kind performance monitoring system for athletes. Simply put, it tells you how hard you worked. No more guessing. WHAT'S IT MEASURE? Armour39 tracks heart rate, calories burned, real-time intensity, and WILLpower. WILLpower is the first true measure of an athlete. It boils your workout down to a single score 0.0-10.0. HOW'S IT WORK? What do you have to do? Aside from workout, not much. It's literally designed for any athlete and any sport. Whatever your workout, Armour39 accounts for every movement and tracks your vitals the whole time. HOW'S IT BETTER? IT MEASURES YOUR WILLPOWER. WILLpower is based on an algorithm that combines how long you workout, what you did, profile info like gender and weight, and key heart rate measures to give you a single score. Set your target every day and go after it. IT GIVES YOU UP -TO-THE-SECOND UPDATES. Only Armour39 shows you instant performance data. Unlike other monitors that only take an average, it precisely captures every heartbeat no matter what you wear it to do. IT SYNCS WITH THE APP AUTOMATICALLY. Armour39 stores your data even if you're not close to your phone. When you get back in range, it transmits your info to the App automatically. IT WORKS FOR ANY WORKOUT. Do the workout you want to do. Armour39 becomes a part of your routine and helps you work smarter.
