Periodisation is the systematic manipulation of training variables — volume, intensity, and frequency — over time to drive continued adaptation. Two models dominate strength training: Linear Periodisation (LP) and Daily Undulating Periodisation (DUP). This is the complete guide for European lifters across the Netherlands, Scandinavia, and Europe, with IPF/EPF competition context throughout.

📋 What Is Periodisation?
Periodisation is the planned variation of training stress over time to maximise adaptation and prevent stagnation. Formalised by Leo Matveyev in the 1960s and further developed by Yuri Verkhoshansky, documented in Supertraining (Siff & Verkhoshansky, 2009). The core principle: the body adapts to any repeated training stimulus within 3–6 weeks — periodisation prevents this accommodation.
📈 Linear Periodisation — How It Works
Volume decreases as intensity increases in a linear fashion over a training cycle.
| Phase | Weeks | Sets x Reps | Intensity |
|---|---|---|---|
| Hypertrophy | 1–4 | 4x10–12 | 60–70% |
| Strength | 5–8 | 4x6–8 | 75–85% |
| Peaking | 9–11 | 3x3–5 | 85–95% |
| Deload/Test | 12 | 1–3x1–3 | 95–100%+ |
🔄 Daily Undulating Periodisation — How It Works
Volume and intensity vary within the same week — different rep ranges trained on different days, developing multiple qualities simultaneously.
| Day | Focus | Sets x Reps | Intensity |
|---|---|---|---|
| Monday | Strength | 4x4–6 | 80–85% |
| Wednesday | Hypertrophy | 4x8–12 | 65–75% |
| Friday | Power/Speed | 5x2–3 | 85–95% |
🔄 LP vs DUP — Head-to-Head
LP vs DUP: linear progression vs weekly undulation across multiple rep ranges
| Linear Periodisation | Daily Undulating Periodisation | |
|---|---|---|
| Variation frequency | Weekly/monthly | Daily |
| Quality development | Sequential | Concurrent |
| Complexity | Low | Moderate–high |
| Best for | Beginners, early intermediates | Intermediates, advanced lifters |
| Accommodation risk | Higher | Lower |
📚 What the Research Says
- Rhea et al. (2002), Journal of Strength and Conditioning Research: DUP produced significantly greater strength gains than LP over 12 weeks — DUP group gained 28.8% on squat vs 14.4% for LP.
- Prestes et al. (2009), Journal of Strength and Conditioning Research: DUP produced greater improvements in muscular strength and endurance vs LP over 12 weeks.
- Colquhoun et al. (2017), Journal of Strength and Conditioning Research: When volume was equated, DUP and LP produced similar strength gains — volume is the primary driver.
- Harries et al. (2015), Journal of Strength and Conditioning Research: Systematic review found DUP superior to LP for strength gains in trained individuals.
📊 Which Popular Programmes Use Each Model
| Programme | Model | Level |
|---|---|---|
| Starting Strength / StrongLifts | Linear (session-to-session) | Beginner |
| Texas Method | Weekly undulating (V/R/I) | Early intermediate |
| 5/3/1 | Monthly linear waves | Intermediate |
| nSuns | Daily undulating (auto-regulated) | Intermediate |
| Sheiko | Block periodisation | Intermediate–advanced |
| Conjugate | Concurrent (ME/DE) | Advanced |
👟 Footwear Considerations
- Across all phases: Use the same shoes throughout your training cycle. Switching footwear between phases disrupts technique.
- Peaking phase: Use the exact shoes you will compete in at your IPF or EPF meet.
- Squat phases: Weightlifting shoes (~€170–€220) recommended for high-bar squatters. Free EU shipping, no import costs.
- Deadlift across all phases: Flat shoes or deadlift slippers.
See our Best Squat Shoes 2026 — Europe guide for recommendations.
🏅 IPF/EPF Competition Context
- IPF and EPF competition preparation typically uses a LP-based peaking block in the final 8–12 weeks before a meet, regardless of the base programme.
- Most successful European competitors use DUP-influenced base programmes (nSuns, Sheiko, custom DUP) year-round, switching to a competition peaking block pre-meet.
- Nordic federation lifters (NPF, SPF, DPF, FPF) and KNKF follow IPF equipment rules — weightlifting shoes are approved for competition squat.
- The progression for most European lifters: LP → weekly undulation → DUP → competition peaking block.
🎯 The Verdict
Use LP if: You are a beginner or early intermediate. Simpler to execute and sufficient for driving adaptation at this stage.
Use DUP if: You are an intermediate or advanced lifter who has stalled on LP. Research consistently shows DUP superior for trained individuals.
FAQ
Is 5/3/1 linear or undulating?
Monthly linear waves — a hybrid between classic LP and DUP.
Which is better for IPF/EPF competition?
DUP-based programmes for the base, LP-based peaking block in the final 8–12 weeks before your meet.
Can I combine LP and DUP?
Yes — block periodisation combines LP phases with DUP within each block. Sheiko uses this approach.
