Today, we are joined by the Director of Sport Initiatives at Spartan Race, Joe DiStefano, aka "Joe DI." If you haven't heard of Spartan, they're a company that has started a movement all across the world, hosting events, training seminars, and all-out, extreme obstacle races that push people to their absolute limits. Spartan is a sport, community, a philosophy, a training and nutrition program – with daily advice, a podcast, a series of books, an activity for kids, workout gear, a media channel, an NBC Sports series, a digital magazine, and a timed obstacle race.

I don't know about you guys, but sometimes, my biggest challenges are overcoming not physical limitations, but mental ones. Often times, when the going gets really tough, I give up on myself, bargain, compromise, or convince myself that I can do it.

That's why, in this episode, we talk with one of Spartan's best and brightest trainers on the topic of mental tenacity. As someone who has helped create some of the world's toughest sporting events, and an acclaimed personal trainer, our guest today has a lot to say on the subject, and I'm sure you'll take away not only a huge dose of inspiration, but also some actionable principles you can use to sharpen your focus and increase your mental tenacity in all of life's challenges.
