Tomtom Runner Cardio GPS Watch
If you're into fitness, you know by now that monitoring your heart rate is pretty much the best way to determine the effect your workout has on your body at any given moment — but you also know what a pain it can be to track consistently. The Tomtom Runner Cardio GPS Watch uses a sensor that casts light through the skin in your wrist, accurately measuring bloodflow without the need for a separate chest strap. With five intensity zones, you can tailor your workout to meet your needs, whether you're training for speed, endurance, or fat loss. And since it's weather resistant, durable, and has a long-lasting battery, you can rest assured it will outlast you on even your best day.
