The short answer
A deload is a planned lighter week: keep the same exercises but cut the number of sets roughly in half, or reduce the load, for about a week. Lifters often schedule one every four to eight weeks, or when performance drops over several sessions. Evidence is still limited, so treat it as a tool, not a rule.
What a deload is
A deload is a short period, usually a week, of deliberately easier training. You keep training the same movements so that technique and routine stay in place, but the total effort drops. It is not a week off, and not a sign that the programme failed.
Signs it may be time
Performance going down on several exercises over several sessions, unusual soreness that lasts, poor sleep, or motivation dropping for no other reason. One bad session is not enough: compare your log over two or three weeks before deciding.
How to lighten the week
Two common options: keep the same weights and do about half the sets, or keep the sets and reduce the load by roughly ten to twenty percent. Stay well away from failure. Pick one approach and write it down so the week is easy to recognise later in your log.
Planned or on demand?
Some programmes build a deload every four to eight weeks. Others suggest one only when fatigue shows up. A 2023 expert consensus in strength and physique sports describes both practices; there are few controlled studies on the topic. If you are a beginner progressing steadily, you may not need one yet.
After the deload
Return to the loads and volume you used before the deload, not to a new peak. The week should leave you feeling fresher. If performance is still dropping afterwards, look at sleep, nutrition and overall volume rather than adding more deloads.
