What Is a Deload? The Planned Light Week | Strongbro
Quick answer
A deload is a planned, temporary reduction in training load, usually a single week, that lets fatigue clear without giving up the adaptations underneath it. The common approach cuts volume by 30 to 50 percent, keeps the same movements, and holds the weight at or a little below normal. Programs often schedule one every 4 to 8 weeks, or trigger one when performance and recovery stall. Logged properly, a deload shows up as an explained dip in your volume chart.
A deload is a week of deliberately reduced training, decided in advance, with a number attached to how much you cut. Then you go back to normal loading. The 2023 international Delphi consensus on deloading (Bell and colleagues) treats it the same way: a planned reduction in training variables, placed inside a programme rather than bolted on when everything falls apart.
What a deload changes
Fatigue builds faster than fitness fades. After several weeks of adding weight or reps, the small aches, the flat sessions and the missed final reps are mostly accumulated fatigue talking rather than lost strength. Lower the stress for five to seven days and that fatigue drains while the strength you built stays put.
Three dials are available: volume (sets), intensity (weight) and frequency (sessions). The usual approach cuts volume hard and barely touches intensity. Heavy but brief work preserves skill and strength. Light but long work is what wears you out.
Here is what that looks like on one lift. Say your normal squat week is 3 sessions of 4 × 6 at 100 kg. That is 12 sets and 7,200 kg of volume. A typical deload keeps all 3 sessions, drops to 2 × 6 at 85 kg, and leaves reps in reserve on every set: 6 sets, 3,060 kg. Volume falls 58 percent, load falls 15 percent. You still practise the movement, the bar still feels like a bar, and the week ends with you wanting to train.
When to take one is the other half of the definition. Programs commonly schedule a deload every 4 to 8 weeks, with the shorter end for higher volumes or heavier loading. The alternative is reactive: you take one when two consecutive weeks show falling reps at the same weight, poor sleep and joints that complain on warm-ups. Both approaches work. Scheduling is easier to keep honest, because the decision gets made before you are tired enough to argue with it.
Logging one
A deload is a deliberate change to your training, and changes that go unrecorded look like problems six weeks later. If monthly volume drops 20 percent and nothing in the log explains why, the review reads as a lost month. If the sets are there at their real weights, the dip is visible and bounded: one pale week in the consistency grid, then the trend resumes.
Logging also protects your working weights. Deload sets are lighter by design, so they will not set personal records. What they will do is become the last-session numbers your app prefills next time. You want to see that the 85 kg was a deload and go back to 100, rather than restart the climb from the light week. The ready-to-progress list in Insights still shows the lifts you had earned an increase on. A deload pauses that clock; it doesn't reset it.
So: log every deload set at its real weight and reps, keep the same exercises so the per-exercise history stays continuous, and stop after the planned week.
Where it goes wrong
Deloading by feel is the common one. A hard week is usually the week that produces the adaptation, and "this feels hard" arrives long before fatigue has actually piled up. Put the deload on the calendar, or write the trigger down, so the call isn't made mid-set.
Cutting everything to zero is the second. A full week off clears fatigue too, but it drops the habit and the skill with it, and the first session back is worse.
Third, dropping the weight while keeping all the sets. Twelve sets at 70 percent is still twelve sets, which is the part you were trying to reduce.
Two smaller ones. An unlogged deload becomes an unexplained gap, so log it like any other week. And a beginner who is still adding weight every session rarely needs one in the first few months; the 4-to-8-week guideline is written for people whose sessions have stopped moving.
For the two terms on either side of a light week, see training volume and progressive overload. The rest are in the glossary.

Frequently asked questions
How often should I deload?
Common programs place one every 4 to 8 weeks, nearer 4 with heavy loading or high volume and nearer 8 with moderate work. Beginners who are still adding weight every session need them less often. If scheduling feels arbitrary, use a trigger instead: two weeks of falling reps at the same weight, with sleep and recovery going backwards.
Should I deload by reducing weight or sets?
Sets first. Cutting volume by 30 to 50 percent clears fatigue quickly, while holding the weight at 80 to 90 percent of normal keeps you used to the feel of a heavy bar. Cut the weight and keep all the sets and you are still doing a lot of work, which was the thing you wanted less of.
Is a deload the same as a week off?
No. A week off is zero training; a deload is reduced training. Both clear fatigue. The deload also keeps the habit, the movement skill and your logging streak, and the return to normal loading is smoother. A full week off is a reasonable choice when life demands one, but it is a different tool.
Will I lose strength during a deload?
Not in a single week. Strength and muscle take considerably longer than seven days to decline, and a deload still trains the movement under real load. What drops across the week is fatigue, which is the thing that was making your working weight feel heavy in the first place.
How do I log a deload so it does not look like a bad month?
Log every set at the weight and reps you actually did, keep the same exercises, and stop after the planned week. The dip then reads as one explained week instead of a vague slump, and your per-exercise history stays continuous, so the next session starts from your real working weight and not the deload weight.
