Polar RS100 Heart Rate Monitor and Stopwatch Review

Average Reviews:

(More customer reviews)It's unisex, easy to use, and has all of the features a runner needs without all of the expensive frills. I chose the RS100 because it had features that the women-specific watches did not, including interval timers, two zone limit monitors, and a back light (essential if you run at night or cross train in spin class where the lights are usually low). I recommended spending a half hour reading the manual and setting up the watch that way. It covers every feature simply and clearly.
Being able to set my own heart rate and percentage limits is great since those numbers change as my fitness improves. I also like that the running total tells me the percent of calories burned from fat, super essential for proper training.
The total only keeps track of one run at a time, which is fine. I log my runs in an Excel spreadsheet and I've found this to be more useful than storing them in the watch because I can write all sorts of formula combinations and create averages and see a big picture and completely geek out. Other models allow you to upload logs to the Polar website but paying the extra money wasn't worth it for me. I like doing that stuff myself.
The medium chest strap fits me fine once it is adjusted (female, 34" chest) and stays in place. Be sure to moisten the transmitters before wearing, a few drops of water will do, your sweat will take care of the rest ...
My only issue is that the watch is a little bulky for my small wrists, which causes some discomfort at times, but I've come up with a few workarounds to solve the bulky problem:
1. I wear it somewhat loose but not so loose that it spins around on its own. This keeps some of the pressure off. It's loose enough that I can manually rotate the face around to the inside of my wrist if I need to.
2. For longer runs, I sometimes wear the watch strapped to my gear belt or zipped in my pocket. Since the watch has interval timers and warning beeps when I go out of zone, I've been able to keep track using my hearing instead of my eyes. The beep is pretty loud so as long as my headphones aren't cranked, I can still hear it.
3. The treadmills at my gym are Polar ready so they pick up the transmission without me having the wear the watch. While the treadmill doesn't have any logging features, I can at least keep track of my heart rate during a run if I don't want to wear the watch.
Overall, it's a great running computer for the money.

In order to reach your fitness goals, you need to exercise at the right intensity. The Polar RS100 wrist heart rate monitor helps you to easily and accurately measure your heart rate to help you get to just the right intensity or your exertion level. This basic HRM features added stopwatch and time-of-day watch features as well as extra-large digits for easy readability. The Time in Target Zone feature calculates the amount of total exercise time spent in your personal target zone. You can use this feature together with the Total Exercise Time to determine the effectiveness of your exercise program.
The RS100 displays heart rate as beats per minute (beats per minute) and as a percentage of the maximum heart rate. The Target Zone feature can be set manually or automatically (for age/weight), and the RS100 provides visual and auditory alarms when you've moved away from the zone. Other features include dual time zone, alarm with snooze, and water resistance to 50 meters.
It's a great choice for using in large groups, where other exercisers might be using wireless training gear that could interfere with your own signal. The RS100's coded transmission prevents crosstalk with other monitors so you'll get a personalized workout--even in a class environment. It also includes the following exclusive Polar features:
Polar OwnCal: This feature shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions. You can set daily and weekly exercise goals in terms of calorie expenditure with the OwnCal feature. Because the OwnCal tracks both the energy expenditure during one exercise session and the accumulated kilocalories during a longer time e.g. one week, it helps in achieving both short term and long term goals.
Polar OwnZone: This feature guides you through an appropriate warm-up routine and automatically determines a safe and effective exercise heart rate zone--your OwnZone--while taking into account your current physical condition.

About Polar The first EKG accurate wireless heart rate monitor was invented by Polar back in 1977 as a training tool for the Finnish National Cross Country Ski Team. The concept of "intensity training" by heart rate swept the athletic world in the eighties. By the 1990s, individuals were looking to heart rate monitors not only for performance training needs, but also for achieving everyday fitness goals. Today, the same concept of heart rate training is being used by world-class athletes as well as everyday people trying to lose weight. Polar is the leading brand among consumers, coaches, and personal trainers worldwide and the company is committed to not only producing the best products, but also being the leading educator on the benefits of heart rate based exercise.
