Linear periodization is characterized by consistent training protocols within microcycles, which are typically one to three weeks in duration. This model involves gradually increasing the intensity of workouts while reducing the volume over a specific training period. The structure allows for a progressive buildup of strength and performance by focusing on a particular goal, often transitioning from hypertrophy to strength, and finally to power.

In contrast, undulating periodization introduces variability within the training cycles, altering the intensity and volume more frequently, often from week to week, which can lead to varied adaptations but does not maintain the same protocols within microcycles. Randomized periodization lacks a structured approach, often incorporating different exercises or training modalities without consistent periods, making it less focused than linear periodization. Dynamic periodization also introduces variability but may not ensure the same level of consistency in microcycles as linear periodization does.

Thus, linear periodization, with its clear and consistent protocol within defined microcycles, effectively creates a straightforward progression towards specific training outcomes.
