The "Kalsu" benchmark WOD was created by John Welbourn of CrossFit Football (now Johnnie WOD). The CrossFit Football website is no longer, so we don't know exactly when it was first posted but the oldest mention we've found from the CrossFit Forum, in October 2009, says the workout was posted by CrossFit Football in June of the same year. On lists of the hardest CrossFit workouts, "Kalsu," is a frequent contender.

See also: "Hotel Hell," a scaled variant of this WOD which substitutes full barbell thrusters with hang squat dumbbell thrusters (35/25 lb).
