Simply stated, periodization is a systematic build of fitness, divided into areas of specific training, with the goal of reaching a fitness peak at a specific time.
This graph shows a typical 4 week periodization cycle over a period of 16 weeks. Ie. Cycle 1 = 4 weeks of progressive build with a rest week on the last week.
