Resolving the childhood obesity dilemma is not as complicated as it's been made out to be according to a former Physical Educator. In the words of Rick Osbourne, "Any coach will agree that kids who can do pull ups are never obese, and kids who are obese can never do pull ups. That being the case, by starting them young, using a height adujstable bar in conjunction with a strategy called leg assisted pull ups, almost any kid can learn to do pull ups. And in the process they'll effectively imminize themselves against obesity for a lifetime, as long as they maintain the ability to pull their own weight. It's about that simple."
