Don’t Let Genetics Limit Muscle Growth

by Josh Hodnik
Genetics are set before birth and our DNA is copied to every cell in our bodies. Our genetic blueprint is passed down from generations. Insulin-like growth factor-1 (IGF-1) is both a gene and the protein it expresses that plays an important role during childhood growth and stimulates anabolic effects. It has been known for more than a decade that IGF-1 and myostatin levels play a determining role in a person’s ability to add muscle from resistance training.
