Today's workout is in honor of Navy Lt. Michael McGreevy, 30, of Portville, New York, who was killed in Afghanistan on June 28, 2005, when the helicopter he was aboard crashed. McGreevy is survived by his wife, Laura; daughter, Molly; mother, Patricia Mackin; and father, Michael McGreevy Sr.

Today, we tackle a longer Hero workout featuring simple movements that heavily tax the lower body and core. Each round should take between 8 and 10 minutes to complete. Scale the run distance as needed to keep each effort under 5:30.

Most athletes should opt for GHD hip extensions rather than back extensions to maintain movement quality and keep intensity high. However, if you can continue moving well and maintain proper form, perform back extensions.

Scale the sit-up volume and/or difficulty so each set can be completed in under 2:15. Focus on steady pacing throughout and aim to stay consistent from round to round.

3 rounds for time of:
800-meter run
25 GHD hip extensions
50 sit-ups
