Ever since I was a little kid, there have been Presidential physical fitness testing requirements in America. You remember them - pushups, sit-ups, chin-ups. Honestly, I never was very good at them until years later, after getting involved in martial arts.

For me, martial arts are a way of staying fit while having fun. But would you believe that now those old Presidential fitness requirements are trying to evolve into something more fun?

Welcome to the 21st century. Now, instead of Presidential physical fitness testing and Presidential physical fitness requirements, I guess you have... The President's Challenge. "The President's Challenge encourages all Americans to make being active part of their everyday lives."
