What training method involves a client training in phases 1, 2, and 5 throughout the week?

The training method that involves a client training in phases 1, 2, and 5 throughout the week is undulating periodization. This approach focuses on varying the intensity and volume of training more frequently—often on a weekly or even daily basis. By incorporating different training phases that target various goals (such as stabilization, strength, and power), undulating periodization allows clients to continually adapt and progress without hitting plateaus.

In contrast, cyclic periodization typically includes longer training blocks that emphasize distinct macrocycles for endurance, hypertrophy, and strength. Linear periodization generally follows a more straightforward progression where intensity increases while volume decreases across weeks or months, not accommodating varying phases within a single week. Block periodization focuses on training in dedicated blocks of time, where each block concentrates intensively on a particular goal, which doesn't align with the alternating phases seen in undulating periodization.

By utilizing undulating periodization, trainers can keep clients engaged and can more effectively address individual needs and recovery, leading to improved adaptations across multiple fitness components.
