When a lifter first starts, he/she is neuromuscularly inefficient. For the first 6 months to a year the CNS adapts quickly to innervate more and more motor units. In effect the gains are rapid and consistent. As the lifter advances this process slows and morphological changes then preceed strength gains unless the lifter focuses on pure strength. The former must focus on increasing motor recruitment and maximize rate coding to increase total motor unit output.
