Questions persist concerning the degree of strength gain between men of differing initial strength levels and muscle masses. The purpose of this study was to compare strength gains in one-repetition maximum (1RM) bench press (BP) in men and women of different initial strength and fat-free mass index (FFMI) levels. Low-strength and high-strength FFMI groups for men and women were derived from a larger group measured for 1RM BP relative to fat-free mass index (FFMI) prior to and following 12 weeks of resistance training. Following training, there was significantly greater (p<0.001) strength gain in men than in women but not a significant difference between high and low FFMI groups (p=0.09). The interaction of sex x FFMI group was not significant (p=0.21). These results suggest men gain more strength than women in absolute terms but when considered relative to FFMI there is no significant difference in strength gain between the sexes.
