PAI’s algorithm is based on data collected from the HUNT study and developed by Professor Ulrik Wisløff, one of the world’s leading scientists in Exercise in Medicine.
The HUNT Study is one of the largest health studies ever and was performed by the Nobel Prize-winning Faculty of Medicine at the Norwegian University of Science and Technology. It contains a unique database of the personal and family medical histories of more than 45,000 people over 25 years.
The American Journal of Medicine
The PAI metric was published in The American Journal of Medicine with the conclusion that PAI can provide people with real insight into how much exercise they need to live longer, healthier lives.
PAI was also validated as a metric that can be used in heart rate devices for people to monitor their exercise levels for maximum health benefits.

PAI Combats Sedentary Lifestyle
A study in the Progress in Cardiovascular Diseases found that PAI can even combat the risk of cardiovascular disease and other lifestyle-related diseases regardless of sedentary lifestyle, such as sitting at a desk for up to 7 hours a day.
The study found that sitting for long periods of time will not increase your risk of cardiovascular disease as long as you maintain a weekly PAI score of 100.
