Strengthen your mind, body, and spirit like a Navy SEAL

What are you capable of? David Goggins' amazing and grueling feat of persistence shows how tough the human mind can be.

What could almost destroy the body and mind of the only person to complete Navy SEAL training (including two Hell Weeks), Air Force tactical air controller training, and U.S. Army Ranger School? David Goggins is tough, but in an effort to raise money for the Lone Survivor Foundation, he took on a challenge that tested him more than any of his military experiences: the Badwater 135. This is an ultra-marathon event that requires participants to run 135 miles in 24 hours in the peak heat of Death Valley. Goggins wasn't a runner at the time; he was a bulky power lifter, and he only had four days to prepare for the qualifying race. He needed to run 100 miles in under 24 hours. So how did he do? Here, he tells the story and in doing so shares a lesson on human potential, mental toughness, and why you won't grow as a person if you always choose the path of least resistance.
