The Paleo diet can be traced back to gastroenterologist Walter Voegtlin, who brought up the idea of eating like our ancestors in 1975 in his book “The Stone Age Diet.” A decade later, researchers Melvin Konner and Stanley Boyd Eaton published a paper on the paleo diet in the New England Journal of Medicine, which is considered one of the foundations of the Paleo diet as we know it today.
CrossFit is a strength and conditioning program consisting mainly of a mix of aerobic exercise, calisthenics (body weight exercises), and Olympic weightlifting. CrossFit, Inc. describes its strength and conditioning program as "constantly varied functional movements executed at high intensity across broad time and modal domains," with the stated goal of improving fitness, which it defines as "work capacity across broad time and modal domains." Hour-long classes at affiliated gyms, or "boxes", typically include a warm-up, a skill development segment, the high-intensity "workout of the day" (or WOD), and a period of individual or group stretching. Some gyms also often have a strength-focused movement prior to the WOD. Performance on each WOD is often scored and/or ranked to encourage competition and to track individual progress. Some affiliates offer additional classes, such as Olympic weightlifting, which are not centered around a WOD.
Anything that comes in a box, jar, or bag should be avoided on the paleo diet—as should anything that just wasn't consumed back then. That means no grains, dairy, added salt, or legumes (including peanuts, beans, lentils, and soybeans), according to Robb Wolf, a former research biochemist, paleo expert, and author of The Paleo Solution. While potatoes are generally outlawed on the diet, Wolff says they are okay to eat sparingly as long as you earn them through exercise (more on that next). Alcohol and honey are also generally considered paleo no-nos, but red wine tends to be the closest option there is to a paleo drink, and honey is far preferred to table sugar or artificial sweeteners.
The final workout of the 2019 Open featured a descending ladder of thrusters and chest-to-bar pull-ups, totaling 105 reps of each movement, with a 20-minute time cap. Last year, 18.5 presented athletes with an ascending ladder of the same two movements, so it’s no surprise that nearly the same percentage of Open participants decided to tackle the final Open workout as prescribed in 2018 and 2019. Read on to see how the community fared with this year's rep scheme.
