Training advancement and adaptation are perfectly obvious principles that are too often ignored, writes Coach Mark Rippetoe of Wichita falls Athletic Club/CrossFit Wichita Falls

Adaptation is the response of the human body to physical stress. And the most fundamental concept in exercise programming is the way adaptation varies among athletes at different levels of training advancement.

The principle of diminishing returns applies quite specifically… Continue Reading

Removing Interference

January 01, 2007

PDF Article

CrossFit makes my brain hurt. Coach Glassman has established a training model for developing fitness that works, and works well. However, the program and its results cannot be easily analyzed with a superficial examination. The system of training is innovative. Conventional exercise science thinking cannot explain why it works as it does. We have to dig deeper to solve this puzzle of human adaptation. The first piece of the CrossFit science… Continue Reading

An Aerobic Paradox

By Lon Kilgore

In ExPhysiology, Reference

December 01, 2006

PDF Article

Have you ever thought about what it is exactly that drives improvement in aerobic work capacity? If you are like most people you probably haven’t really felt compelled to ponder this. Even though I am trained pretty extensively in cardiovascular physiology and training theory, I am an anaerobe and a musclehead. What makes muscle work, become stronger, bigger, or more powerful is my interest.

That means that I hadn't, until recently… Continue Reading

PDF Article

In my article on exercise science in last month's CFJ, I highlighted the difficulty of scientifically determining optimal training methods. Most often, it is coaches working hands-on using a trial-and-error methodology that actually push the science ahead. Eventually, scientists notice that most coaches are doing a particular thing with success and then design a study However, coaches' practical, field-tested insights… Continue Reading

What About Recovery?

By Greg Glassman

January 01, 2005

PDF Article

For the record, my bad attitude towards any established corpus of recovery information stems from several quirks of my intellectual temperament and the nature of my clinical practice. It has been my professional experience that successful training protocols present themselves over time through superior performance among their adherents.

Repeatedly over my career exceptional performance has been easily and quickly rooted out and attributed to the particulars of… Continue Reading

What About Cardio?

By Greg Glassman

June 01, 2004

PDF Article

Conventional wisdom holds that extended bouts of monostructural training (run, bike, swim, row, etc.), commonly referred to as "cardio", confer distinct and powerful advantage to athletic conditioning. This month we explore the proposition that traditional "cardio" may be neither as distinct nor as powerfula contribution to general conditioning as widely believed. In fact, we assert that CrossFit-like programming provides a more effective stimulus for improving cardiorespiratory… Continue Reading

PDF Article

Effective coaching requires efficient communication. This communication is greatly aided by coach and athlete sharing a terminology for both human movement and body parts.

We've developed an exceedingly simple lesson in anatomy and physiology that we believe has improved our ability to accurately and precisely motivate desired behaviors and enhanced our athletes' understanding of both movement and posture.

Basically, we ask… Continue Reading

Metabolic Conditioning

By Greg Glassman

In ExPhysiology

June 01, 2003

PDF Article

Metabolic training refers to conditioning exercises intended to increase the storage and delivery of energy for any activity. Generally, all out efforts of two minutes or less are anaerobic while efforts lasting more than several minutes are aerobic. In this article, Coach Greg Glassman writes why the Crossfit approach is superior for getting results.

Anaerobic efforts are relatively high powered, while aerobic efforts are relatively low powered. Aerobic exercise is nearly universally regarded as being heart… Continue Reading
