What is the benefit of a heart monitor?
Many people today are switching to the heart monitor as the cheapest form of coach they can get. It is ideal for telling us when and how hard to train. It can indicate if we are better off taking a day off or whether we should be pushing ourselves harder. Most models today are wireless, include a stop-watch, have an upper and lower alarm and can record times during your training session. They are also useful during races to keep you below the anaerobic threshold.
