Which principle of training refers to adapting workout intensity based on individual response?

The principle that refers to adapting workout intensity based on individual response is progressive overload. This principle highlights the need to gradually increase the demands placed on the body as fitness levels improve. By adjusting the intensity of workouts in response to how an individual feels—such as their ability to perform exercises, recover, and handle increased workloads—trainers can ensure that the training remains effective and promotes continuous improvement.

Incorporating progressive overload promotes the adaptation of muscles, improving strength, endurance, and overall fitness. It is essential for avoiding plateaus and fostering further development. This principle emphasizes individualized training, as what works for one person may not be suitable for another, necessitating adjustments based on personal progress and response to training stimuli.
