Volume

Do warm-up sets count as training volume?

Two lifters both write down five sets of bench. The first did two ramp-up sets and three hard ones. The second did five hard ones. Their logs are identical and their weeks were not.

If you are counting sets to decide whether a muscle is trained enough, that difference is the entire question. And if you are also trying to work out whether you got stronger, the same confusion causes a second, worse problem.

What a working set is

A working set is a set performed at a load and effort intended to drive adaptation. A warm-up set is preparation for those sets: submaximal on purpose, chosen to be easy, done to raise tissue temperature and rehearse the movement.

The distinction is about intent rather than about a percentage. Nobody needs a rule saying a warm-up is under 60 percent of working weight, because you already know which sets you meant as training and which you meant as preparation. The rule that matters is only that the log knows too.

A back-off set is a common edge case and it is training. It happens after the working sets, at a reduced load, usually for more reps. It was meant to do something. It counts.

The volume problem, which is the obvious one

There is a useful working band for weekly volume: roughly four to ten hard sets per muscle group per week. Under four and there is not enough there to drive much. Over ten and the fatigue keeps scaling while the returns stop being reliable.

That band is only meaningful if the sets in it are the same kind of thing. Count warm-ups and a chest sitting at six real working sets a week reports as ten or eleven. It looks well inside the band. It looks, in fact, like a muscle group you should probably leave alone.

So you leave it alone, and it does not grow, and nothing in your log explains why. The number said you were training enough. The number was counting your ramp-ups.

The error runs the other way too, and it is more expensive. If your chest genuinely is at fourteen hard sets a week and you are wondering why you are always beaten up, an inflated count buries that too, just in the other direction: you cannot see the real figure because it is mixed in with sets that cost you nothing.

The progress problem, which is the one people miss

This is the part that actually breaks things.

Whether you progressed on an exercise is judged by comparing your first working set today against your first working set last time. First set, because it is the only one in the session not carrying fatigue from the sets before it.

Now leave a warm-up unmarked. It is the first set in the list, so it becomes the set your progress is measured on. You benched 40 kg for 10 easy reps to get loose, and that is now your baseline for the exercise.

Next session you warm up differently, or you skip straight to work, and your first set is 80 kg for 8. Compared against a 40 kg warm-up, the comparison is meaningless. Compared the other way, an easy warm-up recorded as a big rep count can make your real working set look like a collapse.

Either way you get a confident verdict computed from a set you deliberately kept easy.

Why the first set is the one that counts

It is worth being clear about why the judged set is the first working set rather than your best set or an average.

By set two you are fatigued from set one, and how fatigued depends on how long you rested. Rest varies with how busy the gym is and how you feel. So set two carries a variable you did not intend to measure, and set three carries more of it. Averaging spreads that variability across everything.

Set one is the cleanest read on capacity you get. It is the set where the only thing that changed since last week is you.

Which is also why warm-ups have to be excluded rather than merely deprioritised. They are not a lesser measurement to be weighted down. They are not a measurement at all.

What warm-ups do to everything downstream

Once warm-ups are in the working-set list, several other readings quietly go wrong at once.

• Rest-period signals. A large rep drop between consecutive sets suggests you did not rest long enough. A warm-up sitting between two working sets produces a fake drop from a set that was never hard.
• Warm-up quality flags. If a later set beats your first, that usually means your first set was under-prepared or sandbagged. That signal is only meaningful when the first set was a real attempt.
• Stall detection. Stalls are counted in consecutive sessions without progress. Verdicts computed off warm-ups produce a scattering of false stalls and false recoveries, and a stall counter that resets on noise never fires when it should.

All four failures come from one unlabelled row. That is the case for the label being worth the two seconds.

The practical version

Mark warm-ups as warm-ups. That is it.

Do as many as you like, at whatever loads suit you. Nothing here is an opinion about how you should prepare to lift, and there is no number of ramp-up sets that is correct. Warming up more thoroughly is not something your log should punish you for, and it will punish you for it if it cannot tell the two apart.

Then, when you count your week, count only the hard sets, and read them against four to ten per muscle group. That number will often be lower than you expected, which is usually the useful part.

Common questions

Do warm-up sets count toward weekly volume?

No. Weekly set counts mean hard working sets. A ramp-up at 40 percent of your working weight is preparation, and counting it makes a muscle group look better trained than it is.

How many warm-up sets should I do?

There is no single number worth quoting, and how you warm up is your call. What matters for tracking is only that whatever you do gets labelled as warm-up rather than counted as training.

Does a warm-up set affect whether I progressed?

It should not, but it will if your tracker cannot tell the difference. A verdict is judged on your first working set, so a warm-up mistaken for a working set becomes the number your progress is measured against, and it is a number you deliberately kept easy.

What if I forget to mark a set as a warm-up?

You get a wrong baseline, and it can persist. The following session gets compared against a set you never intended as a measurement, which usually reads as an unexplained regression when nothing went wrong.

Is a back-off set a warm-up?

No. A back-off set comes after your working sets, at a reduced load, and it is training. A warm-up is preparation done before the work, at a load chosen to be easy.
