For the athlete or workout warrior who wants to see, in real time, how hard he or she is going in the gym, Under Armour’s Armour39 fulfills the need. Wrapping snugly around your chest, without jostling up and down as you put your body through a grueling workout, the Armour39 measures important training statistics like your heart rate, the amount of calories you burn, intensity and WILLpower—a single score of how hard you worked out.
With either an app on your smartphone or a display watch sold separately, you can check your progress as you go and either ramp things up to meet your goal or blow it out of the water if you’ve already surpassed it. Designed for the athlete who wants to know how he or she can improve in the training space, the Armour39 will bring your workout to the level you and your coaches and trainers want it to be by providing the stats you need to get better.
The chest strap ($100) and display watch ($200) can be found at underarmour.com
