Improve your running performance with just 1 plyometric exercise
What is plyometrics? A concept that emerged in the 70s and became popular in the 90s, it consists of repeating a relatively simple movement, composed of an eccentric contraction (rapid stretching of the muscle), immediately followed by a maximal concentric contraction (shortening of the muscle). In other words, plyometrics is often described as a series of rapid, repetitive, and short-duration jumps.
