Omron HR-100C Heart Rate Monitor

Omron HR-100C heart rate monitorThis is Omron’s only heart rate monitor product, yet it is – according to - by far the most popular heart rate monitor on the market. At it boasts an amazing total of more than 550 customer reviews, with more than three-quarters of them four-star or five-star reviews. It retails for $59.99, but by shopping around you should easily be able to buy it for under $35.

Specifications are available at the Omron website. Here are some details:

The Omron HR-100C Heart Rate Monitor is easy to program and a cinch to wear with a ventilated watch band. Knowing your heart rate is important because if you're working out too hard, your activity can actually become counter productive and strain or damage muscles.

To achieve an effective workout, no matter what the aerobic activity, you must maintain your heart rate at a proper level for a minimum of 20 minutes. In general, the proper level falls between 65 percent-85 percent of your maximum heart rate. To ensure you don't drop above or below your proper level, the HR-100C is built with an alarm option that indicates low and high heart rates.

Omron includes a chest transmitter belt with the wristwatch-style monitor. This transmitter sends data to the receiver on your wrist at a distance up to 98 feet (30 meters). The HR-100C is built with a backlight function for exercising after nightfall, and it also displays time of day and a daily reminder alarm feature. Also included is a mounting bracket that makes it easy to attach the watch receiver to most treadmills and bicycles and a soft, zippered storage case.

A short review at Running & Jogging said:

I’ve heard very few bad things about the Omron HR-100C heart rate monitor over the years and, personally, I think it is the best basic heart rate monitor on the market. It doesn’t cost a fortune, is easy-to-use, durable, and accurate. What more could you ask for? The one complaint I’ve heard about this product is that the chest strap and watch band are too big for very petite women. This is a common problem among heart rate monitors, unfortunately; if you are petite, be very careful about which HRM you buy (or make sure they will refund you if it doesn’t fit). For those of you that aren’t very petite women, this HRM is a superb find.

Simply Fitness commented:

The Omron HR-100C may not be the most accurate wireless heart rate monitor and readings are reported to fluctuate a little...but if you are using this for casual exercise and improving your general fitness this is unlikely to cause problems. If more accuracy is important to you and you still want a simple to operate heart rate monitor watch take a look at the Polar F6 heart rate monitor.

Here is an excerpt from one of the many five-star reviews:

The monitor, which displays the time as well as your heart rate on a watch, works in conjuction with a gizmo that you strap around yourself, just under your chest. (I will tell you, since I was concerned about this, that it's hardly noticeable once it's in's a 12" or so long piece of plastic with an adjustable elastic strap...not very bulky at all!) The monitor also features a stopwatch and an alarm, so that after you set your minimum & maximum desired heart rates, you can be alerted when you are out of range. The alarm is a "beep-beep" that I can hear over the book on tape I drag along with me. Your heart rate is updated every second or two so you will always know if you need to pick up the pace a bit.

Although I have not yet had to do so, the chest strap has a removable backing, and you apparently can change the battery yourself (this is a big deal, I guess, since some of the more expensive monitors require that you send them to the factory for a battery change). The elastic strap is also completely removable, which makes it very easy to wash (and you will need to if you're exercising!).

The monitor comes packaged in a small, zippered carrying case, and includes an attachment that allows you to place it on a bicycle handlebar.

This does everything I need it to, and I recommend it for anyone who is just getting started in an exercise program.
