Have you ever felt fine right after exercise, then woken up sore the next day? That delayed muscle ache has a name: DOMS, which stands for delayed onset muscle soreness. It often appears twelve to twenty-four hours after a workout and can peak around forty-eight hours. DOMS is common when you try a new sport, lift heavier, or run farther than usual. It feels stiff and tender, but it usually means your muscles are adapting.
⏰ TIMING
DOMS is delayed. The worst soreness often hits one to two days after the new challenge, not during the workout.
