Deload Need Estimator
Estimate whether you need a deload, how long it should last, and what intensity to target during it based on recent RPE, missed reps, and recovery signals.
Know when to deload—and how aggressively
The Deload Need Estimator helps you decide whether you should deload now, next week, or not at all based on how hard your sets felt (RPE vs your usual RIR target), how many reps you missed recently, and your recovery/plateau signals. It’s built for strength and hypertrophy lifters who track sets and want a practical deload length and intensity target instead of guessing.
From RPE, missed reps, and recovery signals to a fatigue score
First, the tool converts your reported RPE into an “RPE deviation” compared to what you’d expect for your typical RIR goal. It then blends that with (1) missed reps rate, (2) recovery status, and (3) plateau trend to produce a Fatigue Score (0–100). Finally, it applies simple decision rules to output a deload verdict plus a recommended number of deload days and an effort/intensity target.
When “missed reps” should override everything else
Missed reps are treated as a strong fatigue/intent mismatch signal. Even if recovery feels “Great” and your plateau is marked “Improving,” a high missed-reps rate still pushes the recommendation toward deloading because it may reflect technical breakdown, but more often it’s the first sign your load is exceeding your current readiness. Likewise, if your plateau is regressing, the tool avoids under-deloading by extending duration when fatigue signals are high.
Common input combinations that can mislead you (and what the tool does)
If you choose a very strict typical RIR (like 0–1) but also report high missed reps, the estimator interprets it as effort intolerance and will likely call for a deload sooner. If you mark “Improving” but missed reps are high, you’ll still tend to get a deload—because the tool prioritizes the performance failure signal over the trend label. If your window only includes a couple of sessions, results can lag behind real fatigue changes, so consider rerunning after one more week of data.
Use this for planning—not as medical advice
This estimator assumes missed reps and elevated RPE are mainly fatigue/recovery related; it may not be accurate if missed reps come from injury, pain, major technique changes, or poor programming choices (e.g., sudden volume spikes). Deload length is a guideline; sleep, stress, nutrition, and overall weekly volume can require a longer recovery than the calculator suggests. If you’re dealing with persistent pain, worsening symptoms, or form degradation, address that directly rather than relying on deload timing alone.
