Why the Adjustment?

Fatigue accumulation: Sets 3 and beyond accumulate ~1-2% additional fatigue per set. The adjusted weights above already account for this so each set targets a consistent stimulus level rather than progressively grinding harder.

About Program Translator

The Program Translator bridges the gap between percentage-based programming and RPE-based autoregulation. Traditional programs like 5/3/1, Texas Method, and Sheiko prescribe weights as a percentage of your 1RM - but those percentages assume you feel exactly the same every training day.

In reality, daily readiness varies significantly due to sleep quality, life stress, nutrition, and accumulated fatigue. A prescribed 80% day might actually feel like RPE 7 when you are well-rested, or RPE 9 when you are run down.

How Readiness Adjustment Works

The translator applies a readiness modifier to your prescribed percentage before calculating the actual training weight:

  • Great (+3%): Well-rested, motivated, feeling strong - you can handle a slightly higher stimulus than prescribed
  • Good (+1%): A normal good training day - slight upward nudge
  • Average (0%): Use the prescribed weight as-is
  • Below Average (-3%): Tired or stressed - reduce load to maintain the intended stimulus quality
  • Bad (-5%): Run down - significant reduction protects against junk volume and potential injury

Fatigue Accumulation Across Sets

As you perform multiple sets, your capacity decreases. The set-by-set breakdown accounts for ~1-2% additional fatigue per set starting from set 3, automatically adjusting weights to preserve the target RPE across your entire working volume.

Which Programs Benefit Most?

Any percentage-based program benefits from readiness adjustment, but the impact is greatest for programs with multiple heavy sets at high percentages - like 5/3/1 at 85-95% or Sheiko at 80%. These are the zones where small readiness variations cause the largest RPE swings.

Frequently Asked Questions

Yes, when you feel noticeably above or below average. On average days (which is most days), use the prescribed weight. The key insight is that percentage-based programs already assume "average" readiness - so adjusting for bad days prevents junk volume and adjusting for great days captures extra adaptation stimulus you would otherwise leave on the table.
Pure RPE programming sets targets like "4x5 @ RPE 8" with no fixed percentage. The Program Translator starts from your existing percentage-based program and autoregulates within it - letting you keep the structure of 5/3/1 or Sheiko while gaining the flexibility of daily auto-regulation. It is the best of both worlds.
Rarely. A bad readiness day with adjusted weights (5% reduction) still delivers a quality training stimulus. Skipping entirely means losing the training frequency. The reduction exists precisely so you can train effectively even on rough days. Only skip if you are truly ill or injured.
Fatigue accumulates within a session. Your first working set at 80% might feel like RPE 7, but by set 4 or 5 the same weight may feel like RPE 8-8.5 due to accumulated metabolic fatigue and neural fatigue. The fatigue-adjusted weights drop slightly each set to maintain the same perceived effort level and protect technique at high set counts.
Yes. Use the Custom option to enter any prescription (sets x reps @ percentage). This works for any barbell program that prescribes percentage-based loads - Westside, Bulgarian Method, GZCLP, Candito, and anything else. The readiness and fatigue math is universal.

Weight recommendations are based on the Tuchscherer RPE chart and general fatigue accumulation research. Readiness adjustments are guidelines - use your judgment on the platform. Individual response to fatigue varies.
