  • Apply periodisation to group and functional settings
  • Use deloads and testing weeks

Before this lesson

Why this matters

Without planned variation, progress stalls and fatigue accumulates. Periodisation gives functional and group programmes a structure that delivers measurable improvement.

Fundamental concepts

Structure of a periodised annual plan A one-year macrocycle is divided into general preparation, specific preparation, pre-competition, competition and transition phases. Above, training volume starts high and falls as the season approaches, while intensity rises; both drop in the transition phase. Each phase is built from mesocycles of roughly two to six weeks, and each mesocycle from microcycles, usually one week, shown with an example sequence of sessions.

  • Macrocycle — long-term plan (months to a year).
  • Mesocycle — 2–6-week block with a specific emphasis.
  • Microcycle — usually one week.

Models

ModelDescriptionSuits
LinearVolume ↓, intensity ↑ over weeksBeginners, single goals
Daily undulating (DUP)Different rep ranges across the weekBusy adults, group classes
BlockConcentrated blocks (e.g., strength → power) [issurin2010]Athletes, advanced clients

A meta-analysis found periodised resistance training produced greater maximal strength gains than non-periodised training [williams2017].

Applying to functional training

Plan deloads every 3–6 weeks or when fatigue indicators rise; details in deloading and fatigue [haff2016].

Common mistakes and misconceptions

Case study

A gym’s functional class runs a 12-week block with repeated benchmark workouts in weeks 1 and 12. Members’ average benchmark times improve by 12%, and injury reports fall after deload weeks are introduced.

Key takeaways

  • Periodisation is planned variation of training to manage fatigue and drive progress.
  • A meta-analysis found periodised resistance training produced greater maximal strength gains than non-periodised training.
  • Undulating and block models suit functional and group formats.
  • Plan deloads and re-testing every 3–6 weeks.
