What type of periodization focuses on constantly changing the stimuli throughout the training cycle?

Undulating periodization is a training approach that involves frequently varying the intensity, volume, and type of exercises within a given cycle. This method allows for a diverse stimuli exposure, which can enhance adaptations by preventing plateaus and boredom, as well as reducing the risk of overtraining. By modifying factors such as repetitions and load on a regular basis—often weekly or even within the same week—undulating periodization effectively supports both strength and endurance development, catering to multiple fitness goals in a dynamic fashion. This variability helps to optimize performance adaptations and keeps the athlete engaged.

Linear periodization, on the other hand, typically follows a set progression over a longer timeframe, while reverse linear periodization modifies the sequence of intensity increase. Block periodization segments training into distinct blocks but does not emphasize the constant change inherent in undulating periodization. Hence, the unique and systematic variability characteristic of undulating periodization makes it particularly effective for athletes seeking to continuously adapt to new challenges.
