Genes play a significant role in an individual’s fitness journey by influencing various factors such as metabolism, body type, and response to exercise. Genetic predispositions can affect how easily one gains muscle, loses weight, or responds to different types of training. Understanding one’s genetic makeup can lead to more personalized and effective fitness strategies. However, lifestyle choices and consistent effort also play pivotal roles, as they can sometimes override genetic tendencies, making it crucial to maintain a balanced approach to fitness and health.
