Concerning Polar
The first EKG accurate wireless heart rate monitor was invented by Polar back in 1977 as a training tool for the Finnish National Cross Country Ski Team. The concept of "intensity training" by heart rate swept the athletic world in the eighties. By the 1990s, individuals were looking to heart rate monitors not only for performance training needs, but in addition for achieving usual fitness goals. Today, the same concept of heart rate training is being used by world-class athletes as well as usual people trying to lose weight. Polar is the leading brand among consumers, coaches, and personal trainers worldwide and the company is committed to not only producing the excellent products, but in addition being the leading educator on the benefits of heart rate based exercise.
