In this episode of Iron Culture, hosts Eric Trexler and Eric Helms discuss various topics including the ongoing debate about the relationship between muscle growth and strength gains. They discuss brand new findings from the largest and longest-running study on resistance training, explore the implications of "apparent" sex differences in strength gains, and emphasize the need for nuanced statistical analysis in understanding the factors that contribute to strength gains and observed sex differences.
