Just 17% of Rx’d Athletes Got to Round Two of CrossFit Open Workout 18.3

We know that every time an Open workout is announced people call it brutal, but the CrossFit Open’s 18.3 workout was pretty darn brutal.

With its AMRAP triplet of toes to bar, hang clean & jerks, and rowing, 18.1 was a punishing, high-rep metcon, and with its one-rep max clean, the 18.2 workout introduced a completely different way to test the body’s limits. (Check out the heaviest cleans from 18.2 here.)

But 18.3 took things to a different level. As a reminder, this is the workout:

Time cap: 2 Rounds for Time with a 14 minute time cap:

  • 100 Double-Unders
  • 20 Overhead Squats (115lbs/80lbs)
  • 100 Double-Unders
  • 12 Ring Muscle-Ups
  • 100 Double-Unders
  • 20 Dumbbell Snatch (50lbs/35lbs)
  • 100 Double-Unders
  • 12 Bar Muscle-Ups

Your score is your time to complete both rounds. If an athlete is unable to complete both rounds, then the total number of reps completed from the workout will serve as your score.

[Look at the faces on these 10 athletes who got their first muscle-up during 18.3.]

This workout tested a lot: your anaerobic output, your endurance, your mobility, your gymnastics, your coordination. And according to a new post published on the CrossFit Games website, just 17 percent of athletes who Rx’d the weight managed to start the second round.

This was an article from Jonathan Kinnick, a lecturer in economics at California State Polytechnic University who publishes statistical analyses of CrossFit® workouts. (You can read about his breakdown of 18.1 here.)

He found that just 25 percent of men and 6 percent of women who used the Rx weights made it past the first round. (When taking into account the different numbers of male and female athletes, it comes to about 16.7 percent of everyone who participated.) Seventy-seven percent of men and 57 percent of women aged 18-34 used the Rx weights.

Kinnick also put together this chart, which gives the distribution of Rx’d scores based on the movement the athlete was performing when they ran out of time. Check out that big spike during the second set of double-unders — that’s where athletes were most likely to run out of time.

Nick is a content producer and journalist with over seven years’ experience reporting on four continents. His first articles about health were on a cholera outbreak in rural Kenya while he was reporting for a French humanitarian organization. His next writing job was covering the nightlife scene in Shanghai. He’s written on a lot of different kinds of things, but his passion for health ultimately led him to cover it full time.Shanghai was where he managed to publish his first health related article (it was on managing diarrhea), he then went on to produce a radio documentary about bodybuilding in Australia before he finished his Master’s degrees in Journalism and International Relations and headed to New York City. Here, he’s been writing on health full time for more than five years for outlets like Men's Health, VICE, and Popular Science.Nick’s interest in health kind of comes from an existential angle: how are we meant to live? How do we reach our potential? Does the body influence the mind? (Believe it or not, his politics Master’s focused on religion.)Questions like these took him through a lot of different areas of health and fitness like gymnastics, vegetarianism, kettlebell training, fasting, CrossFit, Paleo, and so on, until he realized (or decided) that strength training fit best with the ideas of continuous, measurable self improvement.At BarBend his writing focuses a little more on nutrition and long-form content with a heaping dose of strength training. His underlying belief is in the middle path: you don’t have to count every calorie and complete every workout in order to benefit from a healthy lifestyle and a stronger body. Plus, big traps are cool.
