Plyometric

Plyometric involves increasing muscle power, especially in the legs, by the repeated rapid stretching and contracting of muscles, as by rocket-shipping vertically from a squatting position or explosively jumping over objects. The explosive jumps in plyometrics—which is sometimes called “jump training”—were made popular by the Soviet track-and-field team in the 1970s, who incorporated them in preparing for the Olympic Games. In particular, you might be familiar with the “depth jump,” which is used in extreme fitness and strengthening workouts and involves repeated vertical drops from a box or bench followed by an immediate rebound back up.
