    Differences in muscle strength between individuals seem to be mostly explained by differences in muscle mass,[1][2][3][4][5] which is supported by the mechanistic rationale that a larger muscle has greater force-generating capacity.[6] Other contributors to muscle strength include neural factors,[7] such as the threshold at which motor units are recruited and the motor unit discharge rate, and genetics.[8] Additionally, simply practicing the test used to examine strength (e.g., a back squat 1-repetition maximum) can promote increases in strength.[9][10]
