Learn the mechanics of fundamental movements; establish a consistent pattern of practicing these same movements, and, only then, ratchet up the intensity of workouts incorporating these movements. ‘Mechanics,’ then ‘Consistency,’ and then ‘Intensity’– this is the key to effective implementation of CrossFit programming.
“Described decades ago, the Warburg effect of aerobic glycolysis is a key metabolic hallmark of cancer, yet its significance remains unclear. In this Essay, [authors David Sabatini and Peggy Hsu] re-examine the Warburg effect and establish a framework for understanding its contribution to the altered metabolism of cancer cells.”Read MoreCancer cell metabolism: Warburg and beyond

On March 27, 2019, PepsiCo sent CrossFit, Inc. a cease-and-desist letter regarding the artwork accompanying Professor Tim Noakes’ Hyponatremia of Exercise series. CrossFit, Inc. created the image for this series exposing Gatorade’s deadly marketing campaign. The artwork served to elucidate Gatorade’s hydration myths, not advertise or indicate a commercial good or service. As such, it fell solidly within CrossFit’s fair use rights. CrossFit will not comply with PepsiCo’s demands and is prepared to defend its rights to the full extent of the law. CrossFit also will continue to shine a light on the fatal consequences of the food, beverage, and pharmaceutical industries’ efforts to make a profit through the corruption of the health sciences—including nutrition, exercise, and hydration.Read MorePepsiCo Threatens CrossFit, Inc. With Legal Action Over Hyponatremia Image

Professor Tim Noakes highlights key moments in the evolution of official drinking guidelines from 1880 to 2007, focusing on various organizations’ departures from sound scientific practices in the 1980s and ‘90s. He reviews, in particular, the American College of Sports Medicine’s Position Stands of that era, as well as the U.S. military’s similar acceptance of the Zero-Percent Dehydration Doctrine despite the lack of scientific evidence supporting the associated drinking guidelines. As evidence of the danger of these recommendations mounted, the U.S. military began to revise its position. The sports drink industry, however, continued to overlook the risk of overhydration. As Noakes comments, “When commerce becomes involved in science, the rules of proper scientific conduct soon change.”Read MoreThe Hyponatremia of Exercise, Part 7
The knee joint is comprised of four bones: the femur, patella, tibia, and fibula. They combine to create one of the least structurally stable joints in the body. Accordingly, the knee can only move safely in a limited range and pattern of motion, unlike the shoulder or the hip.Read MoreMovement about Joints, Part 6: The Knee

This famous 1984 TIME cover article was published soon after the results of the Lipid Research Clinics Coronary Primary Prevention Trial (LRC-CPPT) were released. The article cemented the idea that dietary cholesterol and saturated fat were linked to heart disease and should be reduced in the American diet. It broadly illustrates the landscape of heart disease thinking and practice at the time, which centered on the well-established diet-heart hypothesis.Read MoreHold the Eggs and Butter
