There are so many choices choose from but If you want to train correctly or improve your fitness level, heart rate monitors are the only way to go. We really like the Garmin heart rate monitors, the Garmin GPS feature will help you navigate back home. Another favorite is the polar heart monitor line, they are a high tech and reliable heart rate watch. And let's not forget the Polar CS300, Sigma Sport and Cateye heart monitor watches as well. So whether it is Cycling, MultiSport, Running or just basic Fitness we have it covered.
