The muscles of the human body are an amazing thing. They start as small pieces of tissue which connect our tendons and bones to one another. They allow the function of moving objects and moving our bodies thorough our normal daily functions. Unlike the bones and tendons, however, muscles are unique in that we are able to grow them through the addition of progressive resistance training. If we force the muscles to move a particular amount of weight beyond their normal training capacity, they will grow in response to this new workload. Once they grow to a point where they can handle the workload, we will have to further challenge them – with an even heavier weight – in order to force them to grow again.
