The human body is made up of many parts that can act as levers; and successful athletes know how to isolate and utilize them. A lever is a rigid structure that pivots on a fulcrum to overcome a resistive force. Similarly, our skeleton and muscles work together to provide mechanical advantage.
Levers can also be used to magnify movement, for example, when kicking a ball, small contractions of leg muscles produce a much larger movement at the end of the leg. Levers are able to give us a strength advantage or a movement advantage but not both together.
With this information, we can conclude that a lever is a rigid structure that pivots on a fulcrum to overcome a resistive force.
