Genetics can influence physical fitness by determining various traits, including muscle composition, endurance capacity, and metabolism. Genetic predispositions can affect how individuals respond to exercise, including the rate of progress in strength training or aerobic capacity. Certain genetic variants can influence susceptibility to injuries or specific health conditions that may impact physical activity levels. While genetics plays a role, it is important to note that environmental factors, lifestyle choices, and dedicated effort also significantly shape an individual's fitness journey. Recognizing the interplay between genetics and lifestyle can empower individuals to maximize their potential.
