Find your "Fitness Age"

This article appears in the Nov. 3, 2013 issue of The New York Times Magazine.

Trying to quantify your aerobic fitness is a daunting task. It usually requires access to an exercise-physiology lab. But researchers at the Norwegian University of Science and Technology in Trondheim have developed a remarkably low-tech means of precisely assessing aerobic fitness and estimating your “fitness age,” or how well your body functions physically, relative to how well it should work, given your age.

The researchers have used all of this data to create an online calculator that allows people to determine their VO2 max without going to a lab. You’ll need your waist measurement and your resting heart rate. To determine it, sit quietly for 10 minutes and check your pulse; count for 30 seconds, double the number and you have your resting heart rate. Plug these numbers, along with your age, sex and frequency and intensity of exercise, into the calculator, and you’ll learn your fitness age.
