Genetics plays a significant role in an individual's fitness potential, influencing factors such as metabolism, muscle composition, and endurance capacity. Some people may naturally possess genes that facilitate quicker muscle recovery or better fat oxidation, impacting their ability to train effectively. However, while genetics provides a foundation, lifestyle choices—like diet and exercise—also play a critical role in reaching one's full potential. Understanding genetic predispositions can help tailor fitness programs to individual strengths and weaknesses, optimizing training outcomes.
