Murph is a CrossFit Hero Workout that stands as a testament to the enduring legacy of U.S. Navy SEAL Lt. Michael Murphy, who died heroically in the line of duty in Afghanistan on June 28, 2005.

Murph was introduced as a CrossFit Hero workout on Aug. 18, 2005, and has become a long-standing tradition observed by CrossFit and a broader global community of athletes. Thousands of CrossFit gyms program Murph each year on Memorial Day as a way to honor Lt. Murphy and all others who have served.
