The core principle of progressive overload is the gradual (not rapid) increase of stress placed upon the body during training. The idea behind this concept is that in order to achieve more strength, muscles need to be trained in a way that continuously increases the volume (number of repetitions) and intensity (percentage value of maximal functional capacity) of the demands placed on it. This is a fundamental concept in various forms of training, such as weight lifting, high intensity training and physical therapy programs.
