Your whole season, planned backward from game day.
Tudor Bompa's linear periodization — the model behind modern strength coaching — sequences training into phases: anatomical adaptation, maximum strength, conversion to power or sport-specific work, then a taper that lands you at peak on competition day. Most athletes improvise this in a spreadsheet. This planner builds the entire macrocycle from two dates and a goal: phase boundaries, week counts, intensity zones, and rep ranges, all dated.
Coaches and self-coached athletes use this at the start of every season: training without a peak date is just exercising. It answers "what should I be doing 8 weeks out?" with dated phases and loads — the planning layer that separates programs from workouts.
Planned variation of training volume and intensity over time, so adaptation accumulates without burnout and performance peaks on a chosen date. Tudor Bompa formalized the model — phases (macrocycles) built from weekly blocks (microcycles) — now standard in strength and conditioning.
Because adaptation plateaus and fatigue accumulates: the same stimulus stops working within weeks, and maximal-intensity training can only be sustained briefly before performance regresses. Phases solve both — each block creates the adaptation the next one converts.
Bompa's answer: 2–3 macrocycles per year for most sports. Each macrocycle ends in a peak followed by a short transition (active rest) phase before the next anatomical adaptation block begins.
