Fitness is more than just lifting weights or running a few miles—it’s about preparing yourself to say yes to life’s opportunities. When you train with a purpose, you gain the confidence to take on challenges you might never have considered before.

I’ve experienced this first-hand. One moment that stands out is when I said yes to a Spartan Race just three weeks before the event. I had no special training for it, but because I maintained a base level of fitness, I felt ready to give it a go. That race turned out to be more than just a fun experience—it was a reminder that being fit is about staying open to opportunities, no matter how spontaneous.

We often think of health as something to worry about later in life. But the truth is, the habits you form in your 30s and 40s set the stage for how mobile, active, and healthy you'll be in your 50s, 60s, and beyond.
