Signs you need a deload: reps stalled or dropped 2 sessions in a row, shoulders/elbows ache, sleep poor, motivation crashing.
The deload (5 days): Cut volume 40%. Run only Mon/Wed/Fri at 60% of normal target reps. Skip GTG. Skip the heavy day. Keep one easy set of rows daily.
After deload: Resume where you left off. Don't restart — your body kept the adaptations.
