Every now and then, you encounter a WOD that seems so awful, so terrible, so nightmarish… that you absolutely have to try it. This is one of those days. The workout is Hero WOD Kalsu, and it goes a little something like this (via BOXROX).


  • 5 burpees at the start of every minute
  • Max rep thrusters in remaining time until you hit 100 thrusters

61/38 kg (135/85 lbs)

Your score is the time it takes you to complete 100 thrusters.

Robert James “Bob” Kalsu was a professional American football player who moved on from his career to serve in the Vietnam War.
