Which is an example of linear periodization?

The correct answer, which exemplifies linear periodization, describes a structured, planned approach to training where intensity and volume are progressively increased over a specific timeframe. In the context of option B, the design involves a clear sequence: spending four weeks in one training phase, followed by four weeks in a different phase. This structured approach allows for gradual adaptation and focuses on specific training goals in each phase, which is a hallmark of linear periodization.

By adhering to this planned progression, individuals can effectively build strength or endurance over time without introducing too much variation in a short period. This systematic increase in intensity helps to prevent plateaus and optimize performance gains, as each phase is tailored to advance the athlete's development systematically.

The other options do not reflect the core principles of linear periodization. For instance, increasing repetitions indefinitely suggests a lack of structured progression and could lead to overtraining or stagnation without adequate phase differentiation. Varying intensity daily and adjusting workouts weekly also stray from the linear approach, as they incorporate frequent fluctuations in training stimuli rather than a steady, gradual increase in intensity or volume over the planned duration.
