Training Methodology
Block Periodization
Block periodization is a training structure that organizes programming into sequential, concentrated phases (blocks), each with a specific dominant training focus. Rather than developing multiple physical qualities simultaneously throughout the year, block periodization develops them in sequence, with each block building on the adaptations from the previous one.
The three-block structure
The classic model uses three blocks: Accumulation (high volume, lower intensity, building work capacity and general strength), Transmutation (moderate volume, higher intensity, converting that base into sport-specific strength and power), and Realization (low volume, high intensity, peaking performance for competition). The logic is that concentrating training stress into specific blocks produces stronger adaptations than spreading the same work across all qualities at once.
Why it dominates college S&C
Block periodization has become the default framework at serious collegiate programs because it maps cleanly onto the athletic calendar. Offseason accumulation, preseason transmutation, and in-season maintenance or realization align with how most sport schedules are structured. It also gives S&C coaches a clear language for communicating with sport coaches about what phase the program is in and why.
Practical considerations
The model works well for individual sport athletes and programs with clearly defined seasons. It becomes harder to apply with sports that have long or ambiguous competitive calendars, or when managing multiple sports simultaneously. In those cases, coaches often use modified versions with shorter blocks or overlapping focuses rather than strict sequential development.
