HABIT MATH: I do a 3-minute deep squat every morning, no exceptions. Those last two words are crucial. Everyone has 3 minutes to spare—but it’s SOOO easy to skip a day. Then two. Individually, those days don’t matter. But over the course of a year, 3 minutes a day adds up to 18 hours. It’s the difference between improvement (in your ankles, knees, hips, and lower back) and decline. Look, I’m the least structured, least rigid person you follow. I don’t keep a schedule or budget. I play everything by ear. But when it comes to habits, I’m hard core. You have to be if you want the result. (My rule is no coffee until the squat is done. And nothing stands between me and my morning brew.)
