You can also plug in your max HR based if you want. It’s pretty quick and if you do it first thing in the morning without a warm up, chances are it will not be accurate, so take note. Your max HR is calculated using a 10 minute endurance test. It is measured based on your maximum heart rate and how close you come to it or hover around it for the duration of your workout. The measure of willpower is kind of fun and unique to Under Armour. Through Bluetooth connectivity it sends the data to either a free app that you can download to your smartphone or directly to a watch ($199) on your wrist bought separately, which can also send the data later to your phone for further analysis.

It tracks the duration of your workout, calories burned, intensity and of course heart rate.

The gist: The Armour39 ($99) is made for any athlete, any sport. I take pride in my reviews as being honest and this is no different.Īs I mentioned in a few previous posts, I have been using the Under Armour Armour39 during my workouts to track my heart rate, calories burned and intensity.
