Another factor that determines an individual's response to strength training and their maximal muscle building capacity is skeletal frame size. There are large correlations between the thickness width of certain joints in the body and total fat-free mass, particularly wrist thickness, as this is positively correlated with lean body mass but negatively correlated with total body fat (Chumlea et al., 2001). It is even possible to calculate one's maximal muscular potential with a rough degree of accuracy from the thickness of one's wrists and ankles (Nuckols, G., 2015). | Another factor that determines an individual's response to strength training and their maximal muscle building capacity is skeletal frame size.

There are also substantial racial differences in average bone thickness and density, with blacks having the thickest bones, then whites; with Asians and south Asians having the thinnest and weakest bones on average (Zengin et al., 2016, Cong & Walker, 2014). | There are also substantial racial differences in average bone thickness and density, with blacks having the thickest bones, then whites; with Asians and south Asians having the thinnest and weakest bones on average (Zengin et al., 2016, Cong & Walker, 2014). | ||
Thus, one could also expect the typical response to resistance training to vary somewhat by race, with there being more 'easy gainers' found among blacks and more 'hard gainers' found among east and south Asians. | Thus, one could also expect the typical response to resistance training to vary somewhat by race, with there being more 'easy gainers' found among blacks and more 'hard gainers' found among east and south Asians. | ||
