How Genetics Impact Muscle Growth: The Science of Building Muscle Mass Through Exercise

How Genetics Influence Muscle Growth: Your genetic makeup has a significant influence on your ability to build muscle mass. It affects everything from your muscle fiber composition to your hormone production and recovery speed. For example, individuals with a higher proportion of fast-twitch muscle fibers tend to excel at building muscle size due to their greater capacity for hypertrophy. Additionally, variations in genes like myostatin can either limit or enhance muscle growth, depending on how the body regulates this gene.
