We're writing up the full reference for the formulas, thresholds, and progression curves used inside Lift Heavy: one-rep max estimates (Epley, Brzycki, Lombardi), Strength Standards, Fatigue Score, training density, and Volume per muscle group.
In the meantime, every number you see in the app is derived from your real sets — nothing is faked, smoothed, or fudged.
Questions before this ships?
Email support@lfthvy.app — happy to explain any specific formula.
