Muscle Recovery Time & Muscle Protein Synthesis (MPS) Hours Calculator
Calculate exact required post-workout muscle recovery hours and the active Muscle Protein Synthesis (MPS) window based on muscle group size (large vs small), training intensity (RPE / failure), and lifter training experience.

Base Muscle vs CNS Recovery Breakdown (Hours)
Exercise physiology metric. Optimal recovery requires adequate total daily protein (1.6–2.2 g/kg) and 7–9 hours of quality sleep.

Calculation Methodology
Small muscle groups (arms, delts) require 24–48 hours, whereas large groups (quads, back, chest) require 48–72 hours. High-intensity training to failure (RPE 9-10) adds 12–24 hours to central nervous system and tissue repair.
