The Benefits of Wrist Pulse Monitor Watches
A wrist pulse monitor watch is a tremendously insightful accessory for anyone who does cardio training. Usually, exercise is measure by the number of repetitions performed or the amount of distance run, but there’s a flaw with this type of measurement: it’s cumulative, meaning that while you might do the number of repetition you intended, you might have spread them out over a longer interval that reduces the amount of exertion performed over the full session.
A wrist pulse monitor, also known as a heart rate monitor (HRM) watch, allows you to focus on the actual intensity of your workout more directly. The concept is simple. The watch determines your age-appropriate maximum heart rate when you enter in your birth date.

You decide a “target zone” in advance for your workout. This target zone is a percentage of the maximum heart rate, so you might choose, for example, that you intend to stay within 60% to 75% of your maximum heart rate during your workout. The watch will repeatedly been when your heart rate falls outside of these lower and upper limits, so you have continuous feedback when you either aren’t pushing yourself enough, or are pushing yourself too heart.
In some cases, the heart rate sensor is integrated into the strap, but a typical HRM watch, like the Polar F4, uses a chest strap with a wireless transmitter to send heart rate data over to the watch. More deluxe models, like the Polar F11, use a coded wireless transmitter to avoid interference from other users of HRM watches.
You probably don’t need a coded transmitter if you work out on your own, but if you go to a crowded gym, it’s very likely that someone else is using an HRM watch and a transmitter, in which case you’ll appreciate getting your signal on a separate channel, since the interference can result in not getting any heart rate data at all.
