Armour 39 Review + Giveaway

Everyone likes to be able to measure things. Goals, weight, progress, and workouts. There have been many heart rate monitors on the market, some glitchy, some just ok, but nothing compares to the amazing technology of Under Armour’s Armour 39.


I love the tagline “never cheat yourself again”, and this device simply won’t allow it. So what exactly does it measure? Heart rate, calories burned, 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.) So what IS a WILLpower score? WILLpower™ is a single score of how hard your body has worked during a training session, on a scale of 0.0 10.0. It accumulates over the length of your workout, taking into account information that includes the length of your workout, body position, intensity throughout, user profile, and key heart rate information. With WILLpower, you can, for the first time, objectively measure a hard day versus a light day. There are two options, both require the chest strap. You can use the strap and your mobile device,* or use the chest strap and the Display watch (sold separately)

If you choose to use your smart phone, you simply download the Armour39 app from the app store, sync it to your chest strap, and begin! There is an optional assessment that I highly recommend doing at the beginning to help the device zero in on your target heart rate.

*Compatible with iPhone® 4S, iPhone® 5, iPhone® 5S, iPhone® 5C, and iPod Touch® (5th gen) Here is an example of your workout overview:


If you are anything like me, you struggle to take “easy days easy, and take cross training days seriously and need to up the intensity. With this device, you set a target so you never take a day too easy or too hard. I love having a goal, and I love looking at my phone, seeing I need to push harder, and then can see the results of “picking up the intensity”. It truly shows how much of your WILLpower you put into each workout, and is a great tool for any athlete. What’s better? Thanks to my friends at Under Amour Women, I am giving away a chest strap here on THLG! This strap retails for $150, and can be used with your smart phone, or you can purchase the watch to go with the strap. Simply follow the rafflecoptor instructions below:

  10. This would be a great tool for my running.
