P90X - Plyometrics 2004 film complet
Plyometrics is a series of drills designed to connect strength with speed to produce power. Also known as jump training, this technique emerged in Eastern Europe in the early 1970s. Coined by American track coach Fred Will, the term derives from the Latin plyo+metrics, or measurable increases. Plyometrics training relates to any activity that requires speed and strength, as it improves your ability to run faster, jump higher, and maneuver in multidirectional sports. If your game involves a court, field, track, mat, pool, ring, rink, or mountain, plyometrics can help.
