Estimated recovery band
23–36 hours
23 h – about 1.5 days
Pain, illness, low calories, dehydration, or new exercises extend recovery. This is not medical advice—stop if you have injury symptoms and see a professional.
Largest lever
RPE proxy
Eccentric-heavy and novel sessions behave like higher stress even at moderate load.
Focus
Upper / lower / full / iso
Full-body days stress more systems per session than single-joint work.
Volume proxy
<45 to 75+ min
Longer sessions usually accumulate more total work even at the same RPE.
Trend
Gentle nudge up over time
Individual outliers exist—use trends from your own training log when possible.
Recovery multiplier
Short vs long sleep
Not a sleep tracker—just a coarse band you select honestly.

Injury, illness, and medications override any online estimate.
Moderate full-body session, 45–75 minutes, age under 30, 7–8 h sleep → about 23–36 hours (23 h – about 1.5 days).
We start from a baseline center time near one day, then multiply by factors for intensity, anatomical focus, session length, age, and sleep. The minimum and maximum spread the center by roughly ±22% and clamp into a sane bound so outputs stay interpretable. That keeps the model easy to audit—open the breakdown in the form—while reminding you that real recovery is multifactorial.
