Most people use body weight to track their health, but the number on the scale tells you very little about the type of fat that actually drives disease risk. You can have a “normal” weight and still carry high levels of visceral fat — the kind most strongly linked to cardiovascular disease, type 2 diabetes, […]
After two decades of research, no controlled study has ever produced overtraining syndrome under experimental conditions. Here is what that means, and what to do when your training is actually not working. 0 controlled studies have successfully produced overtraining syndrome under experimental conditions. Based on the research summary presented in this article There is a […]
This article is based on a real clinical case and is designed to help active individuals understand how to interpret abnormal liver enzyme results in the context of exercise. The Short Answer If you exercise regularly and your routine blood test shows elevated liver enzymes — specifically ALT and AST — there is a significant […]
Whether you’ve been working out for years or are just starting, you’ve likely seen the term “progressive overload” billed as a foundational concept in exercise. It’s the magic bullet, the secret sauce, the one universal truth that every coach and trainer agrees is necessary for making progress. What they don’t agree on, however, is what […]
“3, 2, 1, Go!” The crowd erupts as the athletes get to work for the final event consisting of 40 deadlifts, 20 kettlebell clean and jerks, and 5 bar muscle-ups. Normally, this workout would be an all-out sprint for you, but you feel a bit sluggish from the other 4 workouts you’ve done in the […]
People start working out for all sorts of different reasons, but weight loss is one of the most common. Despite being billed as necessary for weight loss, the effects of exercise on body weight are nuanced. For example, an exercise program that includes both lifting weights and conditioning improves the body composition. In individuals who […]
Collagen is the most common structural protein in the human body, making up about 25% of the body’s total protein content. Its primary role is to provide structural support to connective tissues like ligaments, tendons, bone, cartilage, and skin, though it is found in virtually every tissue, including teeth, eyes, blood vessels, and more.

Over a lifetime, the average human will consume enough energy to fly a Boeing 747 jet from Los Angeles to New York just over 50 times. That’s an enormous amount of fuel to be sure, which speaks to how much nutrition plays a role in not only powering our daily activities, but also our well-being. […]
Strength training plateaus are a normal and expected part of long-term strength development. At some point, most lifters experience periods where strength no longer increases despite continued training. A plateau does not mean that further progress is impossible. Instead, it usually indicates a mismatch between the training stimulus, recovery, and the individual’s current capacity. Understanding […]
Strength training programming is the process of organizing training variables over time to produce specific fitness adaptations while managing fatigue and recovery. A program includes the structured physical activity an individual performs over a given period of time, including exercise selection, intensity, volume, frequency, and effort. Programming is not the same as periodization. Programming refers […]
