A Better Way to Track Activity than Counting Steps



Say you go for an hour bike ride. You’re dripping in sweat and you feel like you’ve burned thousands of calories. You glance down at the activity tracker poised on your wrist and it reads: “10 steps”.

Well, that’s a bit disappointing. You just biked 15 miles and you get credit for next to nothing? That’s because not all activities involve steps. Unlike other fitness trackers, we believe that you should get credit for all your activities, even the ones that don’t involve steps like yoga, biking and rowing.

Focus on Heart Rate

The most accurate way to track the body’s response to activity is through a person’s heart rate, and not step counting. Your heart rate depends on the intensity of your activity and your personal fitness level, taking into account your age, weight and gender. With heart rate, you get a meaningful guideline on how much activity you should be doing to achieve optimal results. Can step counting do that?  


PAI - Personal Activity Intelligence


Introducing PAI: Personal Activity Intelligence. PAI is one simple number - based on your heart rate - that tells you exactly how much exercise you need to do to live a longer, healthier life. All you have to do is keep your PAI score over 100 over a rolling 7-day window. Any activity that raises your heart rate will count towards your PAI score, including that 15-mile bike ride that only earned you 10 steps.

Everyone earns PAI points at a different rate. Your PAI score takes into account your age, gender, and resting heart rate making it personalized to you. For instance, going for a 6-mile hike may be more strenuous for your dad than it is for you. That’s why he might earn 15 PAI points while you would only earn 10. To earn the same number of PAI points, you would need to work harder because you may be more fit than your dad.


How PAI is Better than Other Metrics


1. It’s Simple:

Your PAI score is derived from your body’s response to the most recent 7 days of activity based on your heart rate intensity. The goal is to maintain a weekly minimum score of 100 PAI for maximum health benefits. It’s a simple number to track activity. 

2. It’s Personal:

PAI is calculated based your heart rate data, age, gender, and fitness level. Because your PAI score is customized to your profile, it is more meaningful and accurate for each individual. Whether you are occasional exerciser or a world-class athlete, your PAI score will generate a score based on your body’s response to exercise.

3. It’s Scientific:

PAI algorithm has been validated based on the HUNT Health Study that followed 45,000 participants over a 25-year period. This study was conducted by the Faculty of Medicine at the Norwegian University of Science and Technology, and the results have been published in an article in The American Journal of Medicine. Those who maintain a PAI score of 100 or above can see up to a 25% risk reduction in cardiovascular disease and other lifestyle diseases, extending lifespan by an average of 5 years. 

4. It’s Meaningful:

Other metrics such as steps are an inaccurate way to track activity.  Because not all steps are created equal, and not all activities involves steps. The most accurate way to determine the health benefits from exercise is to look at heart rate data.

5. It’s Flexible:

Since your PAI score is calculated over a 7-day rolling period, it will capture all your activities during the week. It is adaptable to people’s busy lifestyles. Whether you work out more on some days and less on others, you can still maintain your desired PAI score to achieve optimal health.
