Poor posture can create poor results and cause injuries. Dr. John Zimmer explains how to improve posture for best performance and safety.
“Your form sucks.”
This harsh statement is something I politely announce on a regular basis, along with telling the athlete he or she is pulling with the arms or has muted hip function, and it usually comes in response to myriad questions that are either injury- or performance-related.

Dr. Lon Kilgore says paying attention to simple mechanics can help great coaches improve technique and get better results in the CrossFit box.
The human body is a complex system of levers that enables us to perform everything from very basic to extremely complex movements. Individually, levers are simple machines, and we can think of the body as a collection of machines.

The result was over 90 minutes of education about the relationships among glucose, insulin, ATP, protein, body weight and health. This is a dense, fast-moving presentation worthy of multiple viewings. Topics include:

Dr. Steven M. Platek presents a scientific argument in support of the idea that naturally designed movements produce naturally attractive physiques.
Evolution has favored certain movements in different animals because those behaviors have produced two essential outcomes for possessors of the requisite species-specific movements: survival and reproduction—more specifically, being selected as a mating partner.
For example, the kangaroo and the rabbit (or hare) hop. Big cats (lions… Continue Reading
Modern running shoes feature heels packed with cushioning technology—but Dr. Lon Kilgore wonders if they prevent the foot from functioning as it was designed.
The basic structure of the human foot has not changed significantly for some four to five million years. We have supporting arches that carry the weight of the entire body and virtually any load placed upon it. The many joints comprising the arches are quite well endowed with a… Continue Reading
Jason Khalipa may not be working at his full capacity—and how scary is that?
The 2008 CrossFit Games champ clearly has the capacity to do a lot work very quickly, and he’s incredibly strong. He’s also very inflexible, and how much better would his performance be if he could achieve more favorable starting positions and didn’t have to waste energy working against tight muscles?
