Weekly Undulating Periodization (WUP)

Weekly Undulating Periodization (WUP) is a non-linear periodization model that adjusts intensity, volume, and rep ranges on a weekly basis rather than daily. Unlike Daily Undulating Periodization (DUP), where training variables shift every session, WUP modifies workload across weeks, providing structured yet flexible progression while minimizing fatigue and stagnation.

This method is ideal for lifters who prefer consistent programming over the week but still want the benefits of variable progression without constantly changing their workouts session to session.

Core Principles of Weekly Undulating Periodization (WUP)

WUP operates on weekly variations in training focus, allowing lifters to cycle between hypertrophy, strength, and power phases within a single training block.

Weekly Adjustments in Volume & Intensity

Instead of increasing intensity linearly over months, WUP cycles intensity and volume on a weekly basis to ensure continual adaptation.
Each week follows a different training stimulus, reducing the risk of stagnation.

Balanced Development of Strength & Muscle Growth

Rather than dedicating long blocks to hypertrophy or strength separately, WUP balances both throughout the training cycle.
This approach prevents detraining of previously built strength or muscle mass.

Structured Training Cycles for Long-Term Progress

WUP still follows a logical sequence, but avoids the rigidity of Linear Periodization.
Each week shifts the emphasis, ensuring lifters continue progressing without overuse injuries or CNS fatigue.

Recovery-Optimized Progression

Since WUP balances workload over weeks, it avoids the rapid accumulation of fatigue seen in daily undulating models.
This makes it ideal for lifters who need steady progression while managing recovery more effectively.

WUP Training Structure

WUP typically follows a 3-4 week cycle, with each week focusing on a different training adaptation before resetting or deloading.

Example WUP Weekly Layout (Powerlifting Focused)

Week	Focus	Intensity (% of 1RM)	Reps x Sets
Week 1	Hypertrophy	60-70%	4-5 sets of 8-12
Week 2	Strength	75-85%	4-6 sets of 4-6
Week 3	Power	85-95%	6-8 sets of 2-4
Week 4	Deload	50-60%	2-3 sets of 6-8

Week 1 (Hypertrophy Focus):
- Moderate intensity, higher volume to increase muscle mass and endurance.
- Example exercises: Back Squat, Bench Press, Romanian Deadlifts, Rows.
Week 2 (Strength Focus):
- Lower volume, increased load to build maximal strength.
- Example exercises: Pause Squats, Board Presses, Heavy Deadlifts, Overhead Press.
Week 3 (Power Focus):
- Lower reps, explosive intent, often using bands, chains, or plyometric work to increase force production.
- Example exercises: Box Squats, Speed Bench Press, Olympic Lifts, Medicine Ball Throws.
Week 4 (Deload & Recovery):
- Lighter intensity to allow for recovery before the cycle resets.
- Focus on mobility, technique work, and active recovery exercises.

Alternative WUP Training Layout (Bodybuilding Focused)

Week	Focus	Intensity (% of 1RM)	Reps x Sets
Week 1	High Volume	60-65%	4-5 sets of 10-12
Week 2	Moderate Load	70-80%	4-5 sets of 6-8
Week 3	Heavy Strength	80-90%	4-6 sets of 3-5
Week 4	Deload	50-60%	2-3 sets of 6-8

This setup focuses on progressive overload for hypertrophy and strength, making it ideal for bodybuilders and physique athletes.
The weekly variation in rep ranges allows for sustained muscle growth while still incorporating heavy lifts to maintain strength.

Benefits of Weekly Undulating Periodization (WUP)

✅ Prevents Plateaus – Constant weekly variation keeps the body adapting.
✅ Balances Hypertrophy & Strength Gains – Ensures muscle growth while maintaining strength development.
✅ Allows for Sustainable Progression – Weekly adjustments help avoid stagnation while keeping workload manageable.
✅ Easier Recovery Management – Less frequent intensity shifts compared to Daily Undulating Periodization (DUP).
✅ Ideal for Intermediate & Advanced Lifters – Perfect for those who want structured progression but need more variety than Linear Periodization.

Limitations of Weekly Undulating Periodization

❌ Not as Adaptable as DUP – Lifters who thrive on frequent changes may find it too structured.
❌ May Not Work for Beginners – Requires a solid training foundation and understanding of periodization principles.
❌ Less Effective for Year-Round Readiness – Unlike Conjugate Periodization, which allows constant peak performance, WUP still has distinct cycles.

Origins of Weekly Undulating Periodization

WUP was developed as an evolution of Linear Periodization after sports scientists noticed its limitations in maintaining strength across long phases.

Key Contributors to WUP Development:

Tudor Bompa – One of the earliest researchers in modern periodization theory.
William Kraemer – Conducted studies comparing Linear vs. Undulating Periodization, showing the benefits of weekly intensity shifts.
Mike Zourdos – A key proponent of non-linear periodization strategies, particularly in powerlifting.

WUP vs. Other Periodization Models

Aspect	Linear Periodization	Weekly Undulating Periodization (WUP)	Daily Undulating Periodization (DUP)
Training Focus	One strength quality per phase	Multiple qualities per training cycle	Multiple qualities per training week
Progression	Gradual increase in intensity	Weekly variations in intensity & volume	Daily variations in intensity & volume
Adaptability	Fixed structure, predictable	Moderately flexible	Highly flexible
Best For	Beginners & intermediate lifters	Intermediate & advanced lifters	Advanced lifters & powerlifters
Risk of Plateaus	Higher	Lower	Very low

Final Thoughts

Weekly Undulating Periodization (WUP) is a strategic training model that allows for progressive strength and hypertrophy development without stagnation. By adjusting intensity and volume on a weekly basis, WUP keeps training fresh, optimizes recovery, and provides a structured yet adaptable approach to strength progression.

This method is ideal for intermediate and advanced lifters who need a balance between progression and sustainability. Whether you’re a powerlifter aiming for long-term strength gains or a bodybuilder focusing on hypertrophy without sacrificing strength, WUP offers a practical and effective solution.
