Deload week: what it is, and what the evidence can and cannot say
Lifters and runners swear by the planned easy week. A 2023 consensus of strength coaches set out what a deload is and how they use it. It also admitted something most training content leaves out.
contentsWhat a deload is
Key points
- A deload is a planned stretch of lighter training to reduce fatigue and support recovery.
- In a 2023 expert consensus, coaches agreed the usual approach is fewer sets and reps.
- Intensity can stay similar or drop. The panel did not settle on one rule.
- The same panel agreed there are few scientific studies on deloading.
- Sleep and life stress feed into recovery, so a deload works best alongside a decent week of sleep.
What a deload is
In 2023, a team of researchers ran a three-round consensus exercise with strength and physique coaches from around the world. Building on the panel’s input, they defined a deload as a period of reduced training stress designed to mitigate physical and psychological fatigue, promote recovery and prepare for the next block of training.[55]
In practice, that usually means a lighter week placed between harder blocks. It is planned in advance, which is what separates it from simply skipping the gym when you feel tired.
How coaches build one
table · what the coaches agreed
| Statement | Agreement |
|---|---|
| A deload could reduce volume by lowering sets | 100% |
| A deload could reduce volume by lowering reps | 100% |
| Intensity could stay the same while volume drops | 95% |
| A deload could be included in each training block | 100% |
So the common pattern is fewer sets and reps, with weights that may stay close to normal. How long and how often varies with the program.[55]
What it is for
The panel agreed a deload can be used to reduce physical and mental fatigue, promote recovery, and lower the risk of overreaching, overtraining and boredom with the routine.[55] The authors were careful to say a deload is not meant to boost performance in itself.
The honest part
Every coach on the final panel agreed that current deloading practice rests mainly on coaching experience, and that there are few scientific studies on it. The authors added that it is still unknown whether deloading improves adaptation to training, or whether it is necessary at all.[55]
That does not make deloads a bad idea. It means they are sensible practice built on experience, and you should be wary of anyone selling a precise formula.
Stress outside the gym counts too
Hard training raises cortisol while you work,[43] and in one lab experiment, young men who lost a night’s sleep had raised cortisol by the following evening.[12] Your body does not keep separate accounts for training stress and life stress.
A deload week is a good week to protect your sleep, keep hard sessions away from bedtime,[54] and notice how you feel. A few lines a day in a sleep diary will show whether the lighter week changes your nights.
