"Leverage" is likely not the first term that comes to mind when you think about fitness and sports performance. Without leverage, however, you can't achieve any of the typical fitness objectives, such as power, strength, or speed. In fact, leverage is relevant to all basic movements we make.
Archimedes once said, "Give me a lever long enough and a fulcrum on which to place it, and I shall move the world." That statement—a basic explanation of how leverage is created—is mechanical in nature, but it can be translated into human terms.
