Every minute on the minute do 5 burpees then fill the remaining time with thrusters. Goal is to hit 100 total thrusters for time.

This workout is actually a CrossFit Football WOD that is done in honor of Robert James Kalsu who played for the Buffalo Bills in the NFL in 1968. He then left the team to fulfill his ROTC obligation with the Army. He went on to serve his country in the war in Vietnam and was killed in action.

Remember, this is a HERO workout!! Do what you can with it, scale weight appropriately. Make a plan, x number of thrusters, then burpees.

Workout starts with the burpees.

John Wellbourn and CrossFit Football put the Kalsu WOD out in 2009 and it’s been breaking hearts and taking names ever since. The workout is notorious for its difficulty and has been called the hardest WOD ever by more than one person in CrossFit forums across the Internet.

Times range anywhere from the teens to upwards of fifty and sixty minutes to complete depending on your level of fitness, if you choose to scale and how quickly you can do burpees.

The true test in this workout is a test of mental toughness. Because the rep amounts are large and the burpees are frequent, it’s easy to get sucked into the black hole of mental despair during this WOD.

With a little hard work and a lot of grit, this workout is doable. However, it will not be fun.

Who is Kalsu?kalsu WOD

You may have never heard of Bob Kalsu, but he’s definitely someone worth your attention.

Kalsu was an NFL player with an extremely promising career ahead of him. After starting the entire 1968 season with the Buffalo Bills as a guard, he was named Team Rookie of the Year.

Despite the promise of a legendary career, Kalsu put that aside to enlist in the Army in 1969 and was soon shipped out to Vietnam, where he lost his life less than a year later. Kalsu left behind a wife and two young children.

He was 25 years old when he died. The Kalsu WOD was created to honor Bob and his sacrifice for our country.
