Intermediate level heart rate monitors may be used by those starting an exercise program or who are new to using a heart rate monitor, and by those already involved in regular exercise who want to achieve results quickly, effectively and efficiently. They generally have more features than a basic heart rate monitor, but are not as complex as those required by serious athletes such as those training for a marathon. TheHeartBeatMonitor.com offers intermediate level heart rate monitors from Reebok and Cardiosport in both wireless and strapless models. Several digital models are available. All of our heart rate monitors are simple to use and ECG accurate.
