At the Naval Construction Battalion Center in Gulfport, Mississippi this past week, Joe De Sena, the founder of Spartan Race, lead 750 uniformed cadets through one serious, hours-long workout. There was jumping, crawling, push-ups, squats, and hundreds of burpees. "You can bet each and every person has reached the end of their comfort zone," says De Sena. Looking at the first round of the day (workout below), we have little doubt. 

De Sena lead the cadets after a few officers approached him at the Spartan Atlanta race and asked if he was willing to come down and lead a workout "I jumped at the chance to thank those in uniform,” he says. 

Here's the bulk of his grueling workout.

  • 15 Star Jacks
  • Run in place for 1 minute, high knees
  • 15 Burpees
  • Simulated rope skip for 1 minute
