Jeff Galloway may have just made the best argument I've ever heard about making excuses not to exercise.
So you say you're "too busy to exercise". If you read a recent post from Galloway's blog, you'll see that most of our most recent presidents have made a habit of regularly exercising during the course of their day.
So, I'll pose the question again - still think you're too busy to exercise? Tell that to the leader of the free word!
