Patrick Burke has been CrossFitting for five years. This 31-year-old former Marine says the Corps taught him how to dig deep and harness his mental strength.
"There's a high level of suck to our sport and you've got to be mentally tough," he says. "I feel like I can get into 'the suck' and hang out for awhile."
The 2012 Reebok CrossFit Games will re-air on ESPN2 starting Dec. 16.
