Pressing weight overhead has been one of the classic tests of strength for centuries. Pressing barbells, dumbbells, kettlebells, sandbags, logs, bodyweight, etc. all have their place in a well-balanced training program, and all offer slight variations in stimulus and technique. Kettlebells, like dumbbells, have the advantage of permitting either one-arm or two-arm lifts, and they are biomechanically easier on the elbows and wrists than barbells and most odd objects, Regardless of the implement...

Variable Resistance

The laws of physics tell us that a body will continue in its state of rest or motion (constant velocity) in a straight line unless compelled to change that state by external forces exerted upon it. This is Newton's first law of motion, sometimes called the law of inertia. We inherently know that starting that heavy barbell moving is hard but that once we've got it moving it wants to keep going. So heavy lifts have what is called a sticking point where the amount of muscle force that can be...

The characteristics of the large-group approach from last month. Last month I received more inquires about my article than for any other article I've written for the CrossFit Journal. It was significant on several levels. For one thing, I enjoy discussions about dumbbell conditioning and am glad folks are finding the articles useful. It also confirmed my that CrossFit groups are expanding rapidly and that the CrossFit movement is reaching evening deeper into broad fitness circles. The majority...

Nutrition Lecture

Part 1 Avoiding Disease (Video Article) Nutrition can be a touchy topic, like politics or religion, that people take very personally, but good nutrition is the foundation not only for general health but also for high-performance fitness. Much of the public information about diet, particularly the emphasis on low fat and high carbs, has resulted in a near epidemic of obesity and type II diabetes. In this first of a two-part lecture excerpt, Coach Glassman explores some of the science behind...

I was driving home the other night, listening to the radio, and the guy filling in for Art Bell on Coast to Coast AM was talking to some other guy about Nazis, UFOs, the Kennedy Assassination, time travel, and George Bush, and how it all relates to OneWorldGovernment. This, of course, made me think about barbell training, and it occurred to me that good form on the barbell exercises should not be a matter for debate. People should not be entitled to their own opinion about it, any more than...

Greg Glassman

CrossFit workouts emphasize high-skill movements relative to isolation and or machine-based movements because they are, in almost every respect, better vehicles for optimizing fitness for achieving CrossFit's mission of increasing work capacity across broad time and modal domains. In this lecture from a recent CrossFit certification seminar, Greg Glassman looks at the differences among the shoulder press, push press, and push jerk and compares them to the differences between strict and kipping...
