Remember an important point. Muscles produce force, but they also reduce force. The muscle action spectrum includes reducing force, stabilizing force, and producing force. Remember reductionsim versus holism-how are all the parts put together? Understand and research the Myofascial lines: superficial back line, front functional line, back functional line, superficial front line, lateral line, and spinal line. Look into exercises that incorporate into your programs.
