OwnZone
Guides you to train at the right intensity.
Knowing the right intensity to improve your fitness can be a challenge. OwnZone adjusts your heart rate training zone to perfectly match your body’s current physiological condition. By using OwnZone, you can be sure you’re training at an intensity that improves your aerobic fitness.
Smart Calories
Lets you know exactly how many calories you’ve burned.
OwnCal is the most accurate calorie counter on the market. It calculates the number of calories expended during a training session based on your weight, height, age, gender, your individual maximum heart rate (HRmax) and how hard you’re training.
Tip for using OwnCal feature

Body measurement features

Automatic age-based target zone – bpm / %
To help you train safely and effectively, the training computer determines your heart rate target zone limits automatically according to your age-based maximum heart rate (220 minus age). The limits are determined either in beats per minute (bpm), as a percentage (%) of your maximum heart rate, or as a heart rate reserve (% HRR). See also Maximal oxygen uptake (VO2max) and Manual target zone.
Average and maximum heart rate of each lap
Average and maximum heart rate of training
Heart rate – bpm / %
Heart rate is the measurement of the work your heart does. Heart rate can be expressed as the number of beats per minute (bpm) or as a percentage (%) of your maximum heart rate.
HR-based target zones with visual and audible alarm
You can define your target zones for a training session based on heart rate to help define the right intensity. When you are out of the preset zones, the training computer will give a visual and audible alarm.
HRmax (age-based)
The highest number of heart beats per minute (bpm) during maximum physical exertion. For a rough estimate of your maximum heart rate, subtract your age from 220. HRmax is a useful tool for determining the intensity of training as intensity zones can be defined using HRmax. Some Polar products define maximum heart rate during the Polar Fitness Test, see also HRmax (Polar Fitness Test -based).
HRmax (user set)
Manual target zone – bpm / %
This feature enables you to define the target zone as you want and is suitable for your training. You can set the target zone for your training as beats per minute (bpm), as a percentage of your maximum heart rate, or as a percentage of your heart rate reserve (HRR%).
Polar OwnCal® – calorie expenditure
Polar OwnCal calculates the number of kilocalories expended during training. This feature allows you to follow the kilocalories expended during one training session and cumulative kilocalories expended during several training sessions. Some Polar products also estimate the fat-burning percentage (fat% on display), that is, kilocalories expended from fat during a workout which is expressed as a percentage of the total kilocalories burned.
Polar OwnCode® (5kHz) – coded transmission
Coded heart rate transmission automatically locks in a code to transmit your heart rate to the training computer. The training computer picks up your heart rate from your transmitter only. Coding prevents interference from other training computers.
Polar OwnZone® – personal heart rate zone
Polar OwnZone® determines your personal heart rate limits for a training session. Depending on the day and time, your physical state may vary, for instance, if you are stressed or tired, or if you are not fully recovered from your latest training session, Polar can determine that information from your heart rate and guide you to your ideal training zone for that moment.

›Best money I've spent on fitness equipment -James B.
The RS100 is simple to operate, but works in all conditions. I've run in the hot muggy weather and cold snowy weather, and the RS100 worked perfectly. Also, it helps me keep my heart rate during tempo runs and hill training, so I can build my endurance for race day. On rainy days, I like that the transmitter will pair with most of the cardio equipment at my YMCA. The money that I spent on the RS100 was the best money I've spent on fitness equipment.

›I would highly recommend this watch. -Justin B.
I would highly recommend this watch. The RS100 has all the features you could want and isn't overloaded with ones you don't need. It does everything I want/needed it to do in a beginner monitor. I was primarily concerned with heart rate zones, accurate monitoring, and ease-of-use. Polar has nailed it with this product! It has more features than what I've listed, but those were the most important aspects of monitoring to me. I can't go without mentioning the monitors great design too. Good design is design that you don't notice. Design that works great, stays out of the way, and feels like it's natural, or like it's always been that way. This monitor is everything I just stated. I like it so much that I wear it as an everyday watch and also as a HRM. It's extremely well-built and as tough as nails. Again, I would highly recommend this product. You simply won't find a better product for the price!
