Concept: "Triple Extension"

J. Buursma

You'll see pictures similar to the ones above for olympic lifts frequently. This shows a fully open ankle, knee, and hip, which is commonly known as "triple extension".

This is an important concept in most sports because it's the fullest expression of power. Think of a line backer or wrestler: they start in crouched positions and must forcefully extend to move their opponents back. Even you pushing a car out of a ditch requires this concept.

Being aware of this position will help you develop as an athlete. Do you reach this position EVERY time you lift? Whether a 10# medicine ball or 100kg barbell, extending the body will allow better force production.
