    Amazing Product

    • Written by from San Diego

    PROs: zero connectivity issues. comfortable strap. works with wireless headphones. easy to set up, easy to use. app is clean and colorful. don't have to carry phone which is also nice as it stores data until you connect to your phone again. Very accurate heart rate.
    CONs: WILL power is kind of pointless, but you can just ignore it. other than that, I don't really have an issue.. battery lasts for ever, clean, comfortable, works great.

    I can't say enough positive things about the Armour39. What Under Armour has done with this product is unlike anything else on the market. It really makes me push myself to the next level to achieve my WILLpower goals. I will continue to use my A39 for each and every workout from here on out!! Thanks Under Armour!

    This thing takes training to another level. Now I can see how hard I am working simply during the workout and get a total score (Will Power... Love it) for my entire workout. Recommend this to anyone who trains

    As a professional sports Strength and Conditioning Coach I use the Armour 39 with all my athletes for maximal results. This is a great tool to challenge yourself, break personal goals, and work to achieve maximal fitness through heart rate tracking. Best in class from a brand that is best in class.
