Every few weeks somebody asks us to look at their programme because their lifts have stopped moving. Perhaps one time in five the programme is the problem. The rest of the time we ask about sleep and the conversation ends fairly quickly.
What sleep is doing
Training is the request. Sleep is where most of the work of granting it happens. Tissue repair, the hormonal environment that supports building muscle, and the consolidation of movement patterns you practised all lean heavily on sleep.
That last one is worth pausing on. Learning a lift is a skill, and skills consolidate during sleep in the same way that a piece of music or a language does. Somebody sleeping five hours a night is not only recovering less, they are learning the squat more slowly. See learning to squat for how much of that first year is skill rather than strength.
How much
Seven to nine hours for most adults, and the honest complication is that people are poor judges of which end of that they need. The usable test is whether you wake without an alarm at roughly the same time on a free day. If you sleep three extra hours every Saturday, you are running a deficit during the week.
What a bad week does to your lifts
More than people expect. After a run of short nights, most lifters find that a weight they handled comfortably a fortnight ago feels genuinely heavy, their technique gets sloppier late in a set, and their appetite is louder than usual.
None of that means you are getting weaker or that the programme has failed. It means the conditions changed. The correct response is to change the session, not the plan.
What to do in the session after a bad night
- Turn up anyway. A light session is worth far more than a missed one, and training usually improves that night's sleep rather than harming it.
- Keep the lifts, drop the load. Ten or fifteen percent off, and finish every set feeling like you had two more in you.
- Cut the last exercise, not the first. The main lift is the part that matters. The accessory work is the part you can afford to lose.
- Do not chase a personal best. Nothing good has ever come from testing a maximum on four hours sleep.
Tell the coach when you arrive. It takes ten seconds and it changes what gets written on your page. This is not making excuses, it is giving us the information we need to programme honestly, and it is the same principle as the increments in how much weight to add each week.
The changes that actually work
Everybody has read the list. These are the three that members report making a real difference, rather than the full version nobody follows:
- A consistent wake time, including weekends. This does more than a consistent bedtime, because the wake time is the one you control.
- Light in the morning. Ten minutes outside early is worth more than any evening routine. It is free and it is dull and it works.
- Caffeine with a cut off. Caffeine hangs around for far longer than most people assume. An afternoon coffee is still measurably in your system at bedtime. Moving your last one to lunchtime is often the single change that fixes a light sleeper.
What we have not found useful is telling people to fix their whole evening. Anybody with young children, shift work or a demanding job has heard that advice, cannot act on it, and mostly just feels worse.
Recovery that is not sleep
If your sleep genuinely cannot change for the moment, some other things help at the margins.
- Walking. Twenty or thirty minutes most days. Underrated, and the closest thing to a free lunch in all of this.
- Eating enough. Recovery is expensive. Under eating while training hard is a reliable way to feel flat. Protein without the noise covers the part that matters most.
- Genuinely easy days. Not moderate ones. Easy.
- Fewer sessions for a while. Two well recovered sessions beat four you are dragging yourself through, every time.
The season where sleep is not available
New baby, an ill parent, a period at work you cannot get out of. These happen and they last months rather than days, and the answer is not to keep pushing a programme built for better conditions.
We drop the volume, keep two sessions a week, and hold the ground rather than trying to take more of it. People come out of those seasons a little behind where they were, and they come back quickly, which is a much better outcome than the alternative of stopping altogether and returning eighteen months later. Training around a busy life is written for exactly this.
