What is undulating periodization?

Undulating periodization is a training methodology where you perform different types of workouts on different days within the same week or even within the same day. This could involve focusing on power training one day, strength training on another, and hypertrophy (muscle growth) on yet another day. It's different from linear periodization, where you would focus on one specific type of adaptation (like strength or hypertrophy) for an extended period, such as six to eight weeks, before switching to another type of training. Undulating periodization allows for a mix of training types within a shorter cycle, which can keep the training program dynamic and potentially engage different muscle adaptations within the same week or training period 1.
