Remember back in school when the Presidential Physical Fitness Test rolled around? There was no avoiding the gauntlet of push-ups, pull-ups, sit-ups, and more.

Though your PE instructor may now be a distant memory, it's still smart to measure your strength, flexibility, and endurance, just as you measure your blood pressure and weight, says Steven Farrell, Ph.D., the director of professional education for the Cooper Institute, a nonprofit health-education and research center in Dallas. "These tests give you a sense of your overall fitness level and even predict how you'll age," says Farrell.

To see how you rate, take this four-part challenge, designed to mimic the presidential test, by Farrell and Cedric Bryant, Ph.D., chief exercise physiologist for the American Council on Exercise, in San Diego.

Put Yourself to the Test

Your task is simple: After a 5- to 10-minute warm-up (running in place will do), try the four tests on the following pages: Modified Push-Ups, Curl-Ups, Sit-and-Reach, and One-Mile Timed Walk.

Note your rank (for example, average or above average) under Your Score. If you don't like your results, check out the Real Simple Workout Challenge on the last page.
