In the health and fitness arena, taglines often sell the idea of “accept no limits.” After all, we’re supposed to believe in ourselves, push through boundaries, improve exponentially and show them all, right? Dramatic images, big numbers and extreme makeovers get the spotlight. And when people work hard for what they achieve, I think it’s great. My own primary focus on MDA is helping people live their best life with the least amount of pain, suffering and sacrifice possible. To that end, I offer ample positive advice for what to do. Inherent to the bigger picture, however, (and just as critical in my opinion) is the skill of discerning what not to do. Today I’m talking limits—and how knowing where to draw the line is essential to living an awesome life.
