Want to learn more about the jump training featured in P90X Plyo and just about every single Insanity workout? The Art of Manliness just put up a lengthy post (with photos and videos!) entitled "Beginner's Guide to Plyometrics":
Plyometrics were developed by Soviet Bloc scientists during the Cold War. The leading researcher of plyometric training was a Russian scientist named Yuri Verkhoshansky. Dr. Verkhoshansky developed a system of exercises called “Jump Training” that used repetitive jumping in order to increase the speed and explosiveness of Russian track and field athletes. He published the results of his studies on this new form of training in 1964.
During the 1960s and 70s, Soviet Bloc countries dominated the Olympics thanks in part to Dr. Verkhoshansky’s exercises. Seeing that the Americans were getting their asses handed to them by the Commies, American track and field coach Fred Wilt started to investigate how they were training. He saw that the Soviets were doing a bunch of crazy jumps from boxes and skipping around like school children. Wilt took some notes, went back to America, slapped the moniker “plyometrics” on these new exercises, and started implementing them with his athletes.
Since then, sports teams across the U.S. and the world have incorporated plyometrics into their training regimens to help their athletes become faster and more explosive.Read the complete article here.
