NuMetrex Heart Sensing Racer Tank Keeps Tabs on Your Pulse

The sleeveless and somewhat stylish NuMetrex Heart Sensing Racer Tank has special electronic sensing technology integrated directly in to its fabric that monitors your heart rate. A tiny transmitter snaps into a pocket in the shelf bra to send data to a compatible heart rate monitor wrist watch, a cardio machine or other monitoring device.  The Tank comes in several colors including coral, white and black and it is made of quick drying nylon Lycra with a second-skin fit. Ok, sounds good and all but why you want to wear a shirt like this? For starters, by being aware of your heart rate can tell if you whether you are not exercising hard enough to burn fat or if you are exercising so hard that it’s dangerous.
