Understanding RPE Wave Progressions Through the SRA Lense
A recent conversation with one of my elite level male athletes sparked this post. We were breaking down why certain RPE progressions feel great for some lifters yet seem to bury stronger ones before the end of a training wave. That discussion highlighted a subtle but important difference in how Stimulus, Recovery, and Adaptation (SRA) play out depending on how intensity is structured week to week.
When we look at training progression, especially for stronger lifters, understanding how the SRA relationship shifts across a 4 or 5 week block is essential for maximizing results while minimizing unnecessary fatigue.
The Two RPE Models
Let’s compare two common ways to progress RPE across a 4 week wave using triples as an example:
Model 1 - Straight Ascending RPE
Week 1: RPE 6
Week 2: RPE 7
Week 3: RPE 8
Week 4: RPE 9
This linear climb works well for many intermediate athletes because it provides consistent exposure to heavier loads and helps build confidence toward a peak.
However, for stronger lifters (those handling very heavy absolute weights) even RPE 7 or 8 sets can create significant systemic fatigue. By the time week 4 rolls around, they’re still carrying that residual fatigue, which limits both performance potential and recovery.
Model 2 - Lower-Start, Aggressive End Ramp
Week 1: RPE 5
Week 2: RPE 6
Week 3: RPE 7–7.5
Week 4: RPE 9
This alternative structure gives stronger lifters more breathing room early on. The first two weeks serve as a foundation for movement quality, tissue tolerance, and efficiency, while keeping recovery costs low. By week 4, fatigue is better managed, readiness is higher, and output is stronger exactly how we are tailoring this athletes peaking program.
The Graph: What’s Happening Physiologically
In the chart:
The blue line represents the straight ascending RPE model (6→9). It starts at baseline readiness (1.0) and gradually declines as fatigue accumulates. By week 3, readiness dips around 0.95, and by week 4 it falls closer to 0.90. This shows how fatigue compounds faster than recovery can keep up.
The orange line represents the lower-start, end-ramp model (5→9). It maintains a higher readiness level through weeks 1-3 by managing fatigue early, then peaks at week 4 with greater performance potential.
The shaded area between the two shows the readiness gap, the benefit of better fatigue management and recovery timing. By avoiding early overreach, the athlete arrives at week 4 with higher recovery reserve and improved performance capacity.
Why It Matters for Stronger Lifters
Stronger athletes deal with a higher total fatigue load per rep, so…
Even small jumps in RPE carry larger recovery demands.
They take longer to rebound between sessions.
Their SRA window is narrower, precision matters.
By starting lower and ramping harder at the end, they align training stress with recovery timing hitting their heaviest, most productive work when their body is actually ready for it, not when it’s run down.
Key Takeaway
For advanced lifters:
Start lower to manage fatigue early.
Ramp more aggressively toward the end for a sharper peak.
Let SRA guide your intensity, not just momentum.
This wave structure — low → moderate → sharp ramp → peak - consistently leads to better performance and recovery across 4-5 week blocks, especially leading into deloads or testing phases.
