Technique Part 1

By Greg Glassman

Video Article

In his earlier video article "Better Movements" (Oct 2007 CrossFit Journal) Coach Glassman explained that high power functional movements such as the jerk and the kipping pull-up are better exercises--in several critical ways--than their simpler relatives, the press and the strict pull-up.

Strength, as an isolated quality, can be defined and measured as the biological contractile potential of muscle--as how hard your muscles can contract to apply force.

Video Article

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… Continue Reading

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… Continue Reading
