Features - Training & Performance
Training Load Pro™
When you train, the different systems of your body become strained. Training Load Pro™ monitors this strain to provide you with detailed insights.
Training Load Pro™ gives you values for the load placed on both your cardiovascular and musculoskeletal system (Cardio Load and Muscle Load) after every session, and with Perceived Load you can rate how strained you feel - allowing you to see the immediate strain on your body, and monitor training induced strain over the long-term.
Energy Sources
See how much of each energy source your body uses during training, broken down into fats, carbohydrates, and proteins for each session - illustrated as percentages of your total calorie consumption at the end of your session.
Seeing how much of each energy source you used during your session allows you to learn how different intensities affect your energy usage. You can also spot how the main energy source can change during a long session.
Wrist-Based Running Power
When you run, your body is working against gravity and friction, and requires a lot of power to overcome both forces - Running Power is the calculation of your energy output in relation to your work rate, measured in watts - the faster you work, the higher the power.
Polar Running Power from the wrist is unique in the sense that it provides accurate, scientifically-validated data for highly-responsive results consistently without the need for additional sensors - and this can be done only by using your watch.
Swimming Metrics
Easily track your swimming performance with automatic detection of your swimming style, distance, pace, strokes, and rest times.
Improve your swimming technique over time both in the pool (SWOLF score), and open water.
Season Planner
Most athletes can only peak twice a year. With Season Planner, you can plan and customize the training season - whether you’re in your base training period or in preparation for the racing season.
You can set weekly volumes by duration or distance targets, plan training focus areas, and easily create individual workouts or training targets for each sport.
See what is helping and not helping in terms of reaching your goals and ensure you peak at the right time.
Running Program
Choose one of four running events, 5K, 10K, half marathon or marathon, and get a personalized, adaptive training plan that fits you and your goals.
Your personal running program is based on your training history and your current fitness level – with programs ranging from 9 weeks up to 20 months in length, depending on your event and choices.
Each running program consists of three phases and includes five different types of runs, including interval training and long runs. Don’t sweat it, though. Your Polar device will guide you through each workout and give feedback for each session.
Training Targets
Plan your training sessions in advance with customized training targets and save them to your training diary. When it’s to break a sweat, your device will guide you throughout your scheduled session, so you can fully focus on your workout.
You can create interval workouts with heart rate, speed, or power targets, or set simple training goals, such as ‘burn 700 kcal cycling’ or ‘run 30 minutes.’ Your device will alert you when you need to slow down or speed up to make sure your training goes as planned.
Voice Guidance
Stay focus and limit distractions during workouts with real-time feedback through headphones or other speakers paired to your phone. With Voice Guidance, you’ll receive audible alerts when you reach certain distance, complete a lap, meet a training goal, change heart rate zone, and more.
Rather than always having to look at the screen to know your progress, you can simply hear essential metrics while still enjoying your favorite music or podcast.
*Voice Guidance requires an active Polar Flow mobile app connection.
Work-Rest Guide
Work-rest guide analyzes your heart rate during work and rest phases of a session to give you personalized guidance on the optimal time to start working again.
Specifically designed for high-intensity strength training–and perfect for multi-joint, heavy resistance exercises–it automatically detects your highest heart rate during execution of a set. The algorithm will then monitor your heart rate as you rest, and instruct you when you are recovered enough to begin your next set.
Vertical Speed & VAM
Measures the rate at which you climb or descend so you can get more accurate data and insights into your upward or downward movements when you train in varying terrains.
3D Speed factors in the speed you're going on a horizontal plane, and the speed you're going vertically, to calculate your true speed as you move onwards and upwards.
Hill Splitter™
Hill Splitter™ automatically detects all uphills and downhills by using your GPS-based speed, distance, and barometric altitude data.
It shows you detailed insights into your performance, such as the distance you have traveled, the speed you covered it, and how much you climbed or descended on every detected hill during your session, automatically adapting to the terrain you are training on with every effort counted.
Running Performance Test
Run at the right level.
The Running Performance Test helps you personalize your heart rate, speed and power zones, so that you’ll always hit the optimal running pace.
Fitness Test
VO2max is a key figure to illustrate your aerobic fitness - in other words, the better your aerobic fitness, the stronger and more efficient your heart is.
Fitness Test is a simple 5-minute fitness level assessment that can be performed lying down to estimate your VO2max without needing any other equipment. The automatic calculation takes into account your resting heart rate, heart rate variability, and your personal metrics: gender, age, height, weight, and training background.
Walking Test
Walking Test is an uncomplicated test that you can perform regularly to estimate your aerobic fitness level based on your VO2max.
Walk at a brisk pace for 15 minutes along a flat route and the automatic calculation will factor in the distance you walk, your heart rate during the test, and your personal metrics: gender, age, height, and weight.
FitSpark®
FitSpark® personalized training guide offers daily, on-demand workouts that are easy to do, and match your recovery, fitness level, and training history.
Get new workout suggestions every day for cardio, strength, or mobility direct to your watch - all you have to do is pick the session you like and let your watch guide you through it.
FuelWise™
FuelWise™ is a smart fueling assistant that helps you find the optimal way to fuel during a long training session or event.
To perform better over longer durations, you need to fuel your system with carbs and drink regularly. FuelWise™ gives you smart carb and drinks reminders for you to refuel and help you maintain adequate energy levels during long sessions.
Cycling Performance Test
The Cycling Performance Test helps you follow your progress, allows you to personalize your power zones and tells you your personal functional threshold power.
A compatible power meter is required.
Features - Activity & Health
24/7 Activity Tracking
Our bodies are designed to move, so staying active is essential for your overall health and well-being.
Polar watches promote active lifestyles by giving you a daily activity goal based on your personal data and activity level setting, then automatically tracking your activity throughout the day. If you’ve been inactive for too long, you’ll get a friendly reminder to get up and move. Your daily activity goal is shown as a circle that gradually fills until you reach your goal - get 100%.
Step Count
Counting your steps is a good way to see if you’re doing enough to maintain your overall health. The more steps you take per day, the closer you’ll be to your fitness goals, paving the way to better health.
Going for a walk is an easy way to clock up some steps, but you take a lot of steps every day just by doing everyday things. With a 3D digital acceleration sensor, Polar Watches will measure every move and update your step count as you go.
Inactivity Alert
Inactivity Alert helps you avoid the negative effects of sitting still for too long. Polar products track your movement throughout the day, and when you remain inactive for a prolonged period, the device gently reminds you to get up and move (screen-based products) or the Polar Flow app gives the same notification if it has a Bluetooth connection to your device.
Activity Goal
Activity Goal is a personal daily target for movement and active time, designed around your personal details (such as age, weight, height, and gender) and the activity level you select in the Polar Flow app or web service.
Activity Benefit
Activity Benefit tracks all your active choices during the day and helps you understand the short and long-term effects of your activity and habits on your health and fitness.
With Activity Benefit, you’ll get motivating daily, weekly, and monthly feedback to guide you towards changing your behavior for better health.
The more you move, the greater the health benefits.
Smart Calories
Calculates the number of calories burned based on your individual data: your weight, height, age, gender, HRmax, HRrest, VO2max, and the intensity of your training/activity.
Heart rate-based calorie calculation is used when heart rate is measured, and it measures burned calories the most accurately also in conditions like cycling or lifting weights. Activity-based calorie calculation is used in training computers and activity trackers, when heart rate is not available. You can see the cumulative energy expenditure (in kilocalories, kcal) during exercise and total kilocalories of the session after exercise. You can also follow your total daily calories.
Nightly Skin Temperature
Automatic Nightly Skin Temperature measurement monitors fluctuations in the temperature taken from the surface of your skin on your wrist as you sleep. It then compares that value to your 28-day baseline to display the deviation from your usual range.
* The temperature measurement feature and data is not intended for medical purposes, diagnosis or treatment.
Continuous Heart Rate
Follow your heart rate around the clock with Polar’s continuous wrist-based heart rate solution – an intelligent, dynamic function that works with the 24/7 Activity Tracking feature to provide a more comprehensive measurement for activity intensity.
Your watch will check your heart rate at regular short intervals, and if it detects that your heart rate is elevated, it will start recording automatically.
It factors in a variety of activity intensities, even ones with minimal arm movement, such as cycling, so that they can be counted towards your daily activity goal and calorie burn more accurately.
Features - Sleep & Recovery
Recovery Pro™
Recovery Pro™ works in sync with Training Load Pro™ to give you the full picture of your recovery, letting you know when your body is ready for more training, if you’re training at the right level, or if you should take it easier.
Instead of estimating, Recovery Pro™ actually measures your recovery by monitoring the balance between your training and recovery on a daily basis, and over the long-term.
You get feedback and suggestions that take into account training-induced stress, plus everyday stress outside of training, or bad sleep to provide you with personalized guidance to help you train the right way.
Nightly Recharge™
Nightly Recharge™ is an automatic overnight recovery measurement that shows you how well you recover from the demands of your day. It helps you make the optimal choices in your everyday life to maintain overall well-being and reach your training or fitness goals.
Your Nightly Recharge™ status is based on two components: how you slept (Sleep Charge), and how well your autonomic nervous system calmed down during the early hours of your sleep (ANS Charge).
SleepWise™
Learn how your sleep behavior affects your day’s energy and alertness levels.
With SleepWise™, you get daytime alertness insights that help you perfect a bedtime routine so you can face your daily challenges sharp and ready.
By factoring in your sleep amount, quality, and your body’s internal circadian rhythm, SleepWise™ lets you know how the effects of sleep accumulate over time, making the impact of sleep debt and irregular sleep-wake rhythm visible.
Orthostatic Test
An easy and reliable test to analyze your recovery from training and other life demands – so you’ll know when you’re ready for your next session.
Heart rate and heart rate variability are measured in supine rest, active standing up, and standing states during the test to indicate disturbances in the autonomic nervous system, such as fatigue or overtraining. The results also take several other factors into account, such as mental stress, sleep, latent illness, environmental changes (temperature, altitude), and others.
Orthostatic Test is meant for long-term follow up, based on regular tests.
Leg Recovery Test
The Leg Recovery Test tells you whether your legs are ready for speed and strength training in just a couple of minutes without any specialist equipment – all you need is your watch.
The test is quick and easy to do, and gives clear, guided instructions on how to get the best results. Those results provide you with concrete advice on what type of workout benefits you most at the moment.
Serene™
Relax your body and calm your mind with Serene™ guided breathing exercise.
Deep breathing is known to be an easy and efficient way to manage stress, build resilience and improve focus. Serene™ guides you to breathe at a slow, regular rhythm to synchronize your heart rate with your rate of breathing – six breaths per minute; which is the optimal breathing rate for shutting down your body's stress response.
Sleep Plus Stages™
Getting enough good-quality sleep is vital for your health and well-being. When you sleep, your body cycles through three sleep stages: light, deep, and REM.
Sleep Plus Stages™ automatically tracks the amount and quality of your sleep (Sleep Score), and lets you know how long you spent in each stage during the night.
Sleep tracking can help you understand your sleep behavior over the long-term, and also identify the factors in your day that may have a negative impact on your sleep.
