Essentials

The CrossFit stimulus—constantly varied high-intensity functional movement coupled with meat and vegetables, nuts and seeds, some fruit, little starch, and no sugar—prepares you for the demands of a healthy, functional, independent life and provide a hedge against chronic disease and incapacity. This stimulus is elegant in the mathematical sense of being marked by simplicity and efficacy. The proven elements of this broad, general, and inclusive fitness, in terms of both movement and nutrition, are what we term our CrossFit Essentials.

Null Findings

"Studies that fail to find a positive result are often filed away, never to see the light of day, which leads to a publication bias that compromises the credibility of scientific literature. An analysis now suggests that registering and peer-reviewing study protocols before research is conducted could improve this ‘file-drawer problem’, and help to correct the existing publication bias towards positive findings."

Coupled, the thruster and the pull-up work all major muscle groups, are perfectly complementary in that each contains exactly what the other lacks, and constitute three superfunctional core movements—the squat, push press, and pull-up. But a closer analysis offers even greater appreciation and understanding of Fran’s character.

back squat levers

Despite our relatively inefficient anatomical structure, we still can manage efficiency by considering the body’s interaction with the load and environment and moving the load as close to the fulcrum as possible.

LDL

Uffe Ravnskov et al. argue that recent literature suggesting statins reduce heart-disease risk by lowering total (TC) and LDL cholesterol (LDL-C) is flawed, as is the broader belief in the inverse relationship between TC and LDL-C and heart disease. The authors note: “The usual argument in support of the lipid hypothesis is that numerous studies of young and middle-aged people have shown that high TC or LDL-C predict future CVD. This is correct, but association is not the same as causation.” TC or LDL-C may be effective markers for atherosclerotic risk within an untreated (or minimally treated) population, but this does not mean these markers are causal in the disease state.

Cancer drug molecule

A review of additional scientific literature concerning experiments or studies that challenge the foundation of the somatic mutation theory of cancer, including non-mutagenic origins of metastatic behavior, the absence of gene mutations in cancer cells, the presence of cancer driver genes in some normal cells, and the fallacy of tumor cell growth advantage.

Anatomy of Levers, Part 5

Not all anatomical levers are as obvious or straightforward as the biceps, elbow, and forearm relationship. To understand the musculature involved across the hip, femur, knee, and tibia, along with that required for knee extension, we must consider the attachment point for the force of effort.

Fatty Fig 1

“Non-alcoholic fatty liver disease is the hepatic manifestation of metabolic syndrome; its rising prevalence parallels the rise in obesity and diabetes. Historically thought to result from overnutrition and a sedentary lifestyle, recent evidence suggests that diets high in sugar (from sucrose and/or high-fructose corn syrup) not only increase the risk of NAFLD but also non-alcoholic steatohepatitis.” A review of the experimental and clinical evidence that fructose precipitates fat accumulation in the liver.

"The gymnasts’ unrivaled capacity at hip and trunk flexion is in large part due to their constant training and practice of this exercise." —Greg Glassman
