the proof your muscles are rebuilding stronger by tearing themselves apart first
means The dull aching tenderness felt in muscles or other body parts, especially after exertion, injury, or strain.
from From 'sore' plus the noun-forming suffix '-ness.' 'Sore' descends from Old English 'sar,' meaning pain or grief, with relatives across the Germanic languages — German 'sehr' (now meaning 'very') was once 'painfully,' a cousin that drifted from hurt to mere intensity. The '-ness' ending, also Old English, simply turns a quality into a thing, making 'soreness' the state of being sore.
