I finally looked up something that had been bugging me. You see, for the workout called “Murph” by CrossFit, something was off. CrossFit said to wear “body armor” or a “20lb weighted vest” for the workout, back when it was first announced officially.
However, the workout itself was the workout done by a man named Michael Murphy. He was a Navy Seal. (Wait for it…) And yes, David Goggins trained with and knew him. (He comes up basically every day, now, no matter that I don’t even try.) From a combination of interviews I read that were about him, I learned that he wore the Navy-issue body armor vest while doing the workout. Someone mentioned in the interview – I think it was his dad – that the vest weighed 16.4 pounds, and that Michael would finish the workout, on average, between 32 and 35 minutes. That means that he did, in just over 30 minutes, a mile run, 100 pull-ups, 200 push-ups, 300 air squats, and another mile run, all while wearing a 16.4lb vest.
But the workout says to wear a 20lb vest. What gives?
Well, I finally looked up the government-issue body armor vests, the ones that were (are?) worn by the Navy from, at least, the year 2000 through the year 2017 (possibly still now, but I didn’t delve that deep). It is called the Interceptor Multi-Threat Body Armor System (IBA).
And guess how much the total weight is. Just guess.
It was an upgrade in lightness from its predecessor, which was 25.1lbs and went by a different name, and the latest version apparently weighs 33.1lbs.
So, under no version of this vest would Lieutenant Michael P. Murphy have had a 20lb vest. And, given the years that he was a Navy SEAL, he would have worn the 16.4lb vest. If he only wore the outer shell of it, it would have been only 8.4lbs. Those are the two options. Not 20lbs.
Anyway, I know officially now what my goal weight is for this workout: 16.4lbs in the vest.
