What is the difference between muscle overload and muscle overuse?

Muscle overload refers to the process of increasing the demands placed on a muscle to promote strength and hypertrophy, often achieved through progressive resistance training. In contrast, muscle overuse occurs when a muscle is subjected to excessive strain without adequate recovery, leading to injury or fatigue. While overload is a beneficial training strategy, overuse can result in pain, inflammation, and decreased performance. Balancing the two is crucial for effective training and injury prevention.
