Which of the following is a way to apply progressive overload?

Progressive overload is a fundamental principle in strength training that involves gradually increasing the demands on the body to continuously make gains in muscle size, strength, and endurance. Altering the speed of the movement is a practical application of progressive overload because it changes the intensity of the exercise without necessarily changing the weight or the exercise itself. For instance, performing a lift more slowly can increase the time under tension for the muscles, which can lead to enhanced muscle growth and strength.

Changing the speed of movement can also affect the muscle fibers recruited during the exercise, adding variety and challenge to the workout. By manipulating the tempo, a trainer can focus on different phases of the lift—like enhancing the eccentric (lengthening) or concentric (shortening) phases—thereby increasing the difficulty and effectiveness of the training over time. This method not only includes the physical weight lifted but also challenges the neuromuscular system in a novel way, allowing for ongoing adaptation and progress.

In contrast, maintaining a constant load would not apply the principle of progressive overload, as it does not provide an increase in the training stimulus over time. Switching to bodyweight training may also not introduce increased resistance if the bodyweight is not challenging enough for the individual. Lastly, sticking to familiar
