The last way I’ll discuss how genetics come into play is how easy it is for some people to build muscle. In my interview conducted this was the most mentioned thing in how genetics play a role in bodybuilding. Max mentioned a study that was conducted where “100 subjects were studied and tracked as they were all put on the same strict diet and assigned a personal trainer, and some of the subjects, even when everything was controlled, still saw zero muscle growth over a 3-month period.” In my research, I found that,
Certain genes can not be as present in others that are vital in muscle growth
Certain genes can also cause some people to have a much harder time gaining muscle
“There are several genes that affect muscle development and growth” (ISSA)
They can inhibit or boost your muscle growth
Genetics can also affect your testosterone levels, which is vital in how much muscle you can gain
