Deload week: when, how often and how

What is a deload?

A deload is a short phase of reduced training load, usually one week. An international expert survey of strength and physique coaches worked out a shared definition: a phase of less training stress that is meant to reduce physical and mental fatigue, support recovery and prepare you for the training that follows (Bell et al., 2023).

Less training does not mean standing still. As a rule, the weight on the bar stays about the same while sets and reps come down. That keeps the training stimulus in place and gives your muscles, joints and nervous system some breathing room. The habit of going to the gym stays intact as well.

Do you even need a deload?

Not necessarily. Many people go a long time without one. If you train at a moderate level, look after your recovery and rarely push to your limits, you can often do without planned deloads entirely.

A deload is also not a trick for more muscle growth. In a study of 39 trained women and men, one group took a full week off training in the middle of a 9-week programme. By the end, their leg muscle gains were the same as in the group that trained straight through. Strength, on the other hand, had increased more in the group that kept training (Coleman et al., 2024). So a break does not hurt your progress, but it does not speed it up either. Its purpose is to clear fatigue before it starts holding your training back.

How to tell it is time

The clearest sign is several warning signs showing up together for at least a week. A single weak session is not enough. These are the four signals I look for:

• Raised resting heart rate: measured in the morning right after waking up, and noticeably above your personal baseline.
• Lasting fatigue: tiredness that does not improve even after a normal night's sleep.
• Drop in performance: familiar weights suddenly feel heavier, even though your plan and your eating have not changed.
• Mood: irritability or a lack of drive for no obvious reason, especially around training.

With resting heart rate, a single morning does not count. What matters is the trend over several days. If you write it down for a few weeks, you will know your baseline and spot changes quickly. This fits what competitive athletes do in practice: they often take a deload when their performance stalls or when muscle soreness and joint aches increase (Rogerson et al., 2024).

Planned or as needed: how often?

Both work. The coaches surveyed agreed that a deload can be scheduled in advance, taken as needed, or a mix of both (Bell et al., 2023). In a survey of 246 competitive athletes from strength and physique sports, a deload lasted 6.4 days on average and came roughly every 5.6 weeks (Rogerson et al., 2024). Keep in mind, though, that these were competitive athletes with an average of eight years of strength training, not recreational lifters.

My advice: if you train hard, with high volume, and prefer to follow a fixed calendar, schedule a deload every fifth or sixth week. If you train at a moderate level, respond to the warning signs. In most cases one week is enough.

Four ways to structure a deload

Which option fits depends on what is tired: your muscles, your joints or your head.

For most people, a volume or intensity deload is completely sufficient. That matches what the surveyed athletes did in practice: they cut sets and reps, took a little weight off, stopped further from failure and kept their training days and exercises the same (Rogerson et al., 2024). How to judge how close you are to failure is explained in the article on RIR in strength training.

Example: what a deload week looks like

Let's say a full-body session normally looks like this. Every set ends at RIR 1 to 2, and during the deload at about RIR 3 to 4.

In the volume deload, working reps drop from 94 to 48, so roughly half, at the same weight. In the intensity deload, the reps stay the same and the weight sits at about 65% of the normal load. In both cases the training days stay the same.

How to get back into training afterwards

After a short, planned deload you can usually pick up your normal plan straight away. That is exactly what it is for: the coaches in the expert survey saw it as a chance to push harder again in the next training block (Bell et al., 2023).

If you were genuinely exhausted, though, it is worth building back up over two to three weeks. As a guide, not a fixed rule: in the first week about 65% of your normal volume at your usual weights, in the second about 85% with slightly increasing weights, and in the third your regular plan again. If you still do not feel recovered after the deload, do not tack on a second deload week. Look for the cause instead: sleep, stress, your baseline training volume and whether you are eating enough. The calorie calculator shows you how much energy you need. How to keep progressing from there is covered in the article When should you increase the weight? Progression made simple.

Overtrained or just tired?

Most people are simply worn out after a hard training block, and that clears up within a few days. A short-term dip in performance after hard phases is normal and can even lead to better performance once you have recovered enough. Genuine overtraining syndrome, by contrast, is a longer-lasting maladaptation. It is hard to reliably distinguish from severe overreaching and is diagnosed mainly by ruling out other causes, such as infections, too little energy intake or iron deficiency. So far there is no single reliable marker for it (Meeusen et al., 2013).

In everyday life, one simple question helps: if you want to train again after two easier days and feel noticeably better, you were worn out. If you barely feel recovered even after a whole quiet week, and you are also sleeping badly and lack motivation, take a closer look.

When to get it checked by a doctor

If fatigue, poor performance or a raised resting heart rate persist despite a recovery week, or if physical symptoms such as a racing heart or dizziness come on top, pause your training and have a doctor look into the cause. In case of sudden shortness of breath, chest pain or fainting, call emergency services immediately. This article does not replace medical advice.
