Nike said Just Do It. Gatorade commercials show athletes caught in slow-mo, sweating and bleeding the sports drink. Reebok says, “Why hit the wall? It hurts. Run easy.” And “A 10 minute mile is just as far as a 6-minute mile. Run easy.” Sure, it’s the same distance, but it’s not the same workout. Of course, if it’s a difference between running easy and not running at all, by all means, run easy. Sure, people should have fun working out and not get all killer crazy about it. But, if you want to become fitter, you work yourself up to running faster and harder, not easier.
