Which periodization model alternates volume and intensity from week to week or day to day?

• A. Block periodization
• B. Undulation periodization
• C. Pyramid sets
• D. Linear periodization

Answer: (B)

The concept being tested is how training stress is organized over time. Undulation periodization, also called nonlinear periodization, alternates volume and intensity from week to week or day to day. This means you might have a high-volume, lower-intensity day and a low-volume, higher-intensity day within the same week, or vary volume and intensity across different days. Such frequent fluctuations help stress different fitness qualities, improve recovery, and can prevent plateaus by continually challenging the body in different ways.

This differs from linear periodization, which shifts gradually from high volume with lower intensity to lower volume with higher intensity over a longer cycle; block periodization, which concentrates on one training focus within each block; and pyramid sets, which are a way of ordering sets within a single session rather than structuring long-term variability.
