Remember those fitness tests you had to take in gym class? The ones where you huffed and puffed through the sprint drills, grimaced while reaching for your toes, and, most memorably, sweated and trembled through one dramatic pull-up (or more likely, hung in the air for an interminable "stay-up")? Well, they're back: in adult form. You can now take an adult version of the President's Challenge fitness test online.

The new test, which is free, involves four components: aerobic fitness (a 1 mile walk or 1.5 mile run), muscular strength and endurance (crunches and push-ups), flexibility (the good ol' sit-and-reach) and body composition (your BMI and waist circumference). You don't have to do any of these in front of giggling, gossiping, preteen witnesses, but the test-makers suggest they're more fun with a partner. When you're done, you can enter your data online to see how you measure up to other fit Americans.

We're pretty excited about this. Back in school, the tests seemed like pop quizzes that we didn't have a chance to study or prepare for. Worse, we had to execute all of the moves in front of our friends. But in the past tentwenty-odd years (who's counting?), we've been taking our health more seriously. In the immortal words of LMFAO, we're sexy and we know it--we work out. Even if we don't smoke the test this time, we know can take it again in the future, which means--keep doing those push-ups. It's also fun to know that no matter how we score, we can still buy one of these nifty, nostalgic patches and a completion certificate--just like the one we got many years ago.
