Aging typically leads to a natural decline in muscle mass, a condition known as sarcopenia. This decline can begin as early as the age of 30 and accelerates with age, resulting in decreased strength, endurance, and overall physical function. Reduced muscle mass can negatively impact mobility, balance, and the ability to perform daily activities. Engaging in regular strength training and maintaining an active lifestyle can help mitigate muscle loss and promote healthier aging, enhancing quality of life and functional independence.
