Maybe the answer isn’t trying to get there by inches. Maybe the answer isn’t HR wheedling employees into changes they’re told are easy. Maybe the real opportunity is to say: We’re going to try something crazy difficult, something really intense. Everybody who steps up to do it is going to feel like they’re about to die, albeit for fifteen minutes, twenty minutes, tops. Strong people and not-so-strong people will see one another’s heroic efforts. And in the end, we’ll be more than faster, more powerful, harder to kill, and generally more useful.7 We’ll be a group of people that knows it can do crazy difficult things. Reebok’s CrossFit logo is a big equilateral triangle pointing up—the Greek letter delta, the mathematical symbol for change. If the wellness nudgers can’t save us, if comfortable solutions won’t make us strong again, maybe intensity—the willingness to get comfortable with discomfort—is the only thing that will really make a difference.
