As individuals age, they often experience a natural decline in muscle mass, a condition known as sarcopenia. This process typically begins around age 30 and can accelerate due to factors such as decreased physical activity and hormonal changes. Loss of muscle mass can lead to reduced strength, increased risk of injuries, and diminished functional independence. Engaging in regular strength training and resistance exercises can help combat this decline by promoting muscle preservation and enhancing overall physical performance, contributing to better quality of life as one ages.
