What to Write in a Workout Log When You Have Never Kept One
Practical answer
Write one line per set: the exercise, the weight, the reps. That is the whole format. For dumbbells, pick per hand and never switch; a pair of 20s is logged as 20. Log warm-up sets if they are more than the empty bar, and skip the how-it-felt column until you have a month of numbers to compare it against. Consistency matters more than any of the individual choices, because the log is only useful when this week's line can be laid next to last week's. Say the set out loud or tap it in, and let the app keep the format for you.
You bought a notebook. You opened it on the bench, pen ready, after the first set of dumbbell presses, and stalled. Two 20 kg dumbbells: is that 20 or 40? The two lighter sets before it: do they go in? Should there be a column for how it felt? By the time you have thought it through the rest has started, and the page is still blank. None of these questions matter much, and together they have stopped you keeping a log at all.
The moment, and why it lands so hard
It sounds trivial, and people who ask about it online know that. The question is usually phrased with an apology: how do you log this stuff, would you write 45 or 90, is it exercise then weight then reps. The answers are calm and consistent. One line per exercise is enough. Write weight, reps, how it felt. Whatever makes sense to you and lets you see growth. And that last one is the point, and also the trap.
The trap is that a beginner has no way to judge what will let them see growth, because they have never seen any yet. Every format decision looks equally important and equally arbitrary. So the notebook becomes a series of small choices made under time pressure between sets, and the natural response to that is to stop making them.
The real problem is that the format is not settled
A log is only useful for one thing: comparing this session with an earlier one. That comparison needs the two lines to mean the same thing. A pair of dumbbells logged as 20 one week and 40 the next is not progress, it is a change of convention, and once your history contains both you cannot tell them apart. The same goes for warm-ups in one week and out the next, or an exercise called two different names.
So the thing that stalls you at the first line is real. You are sensing, correctly, that the choices have to be fixed before the log can work. What you are getting wrong is the idea that they have to be the right choices. They do not. They have to be the same choices, every time, for months. That is what a tracker does that a notebook cannot: it makes the decision once, at setup, and then applies it to every set without asking. Training volume, records, and the monthly comparison all rest on that consistency.
What to do when the page is still blank
Six decisions, made once.
1. Settle on one line per set
Exercise, weight, reps. That is the complete record of a set, and it is all a first log needs. Not sets per exercise, not rest times, not a rating. Three sets of eight at 60 kg is three lines, and the moment the third set drops to six you will be glad they were separate. In Strongbro the keypad is built around exactly this line: weight × reps in large digits, one arrow to log the set, each set appearing as its own pill. There is no other field to fill in, which is the point.
2. Fix the dumbbell convention
Log dumbbells as the weight in one hand. A pair of 20 kg dumbbells is 20, and a pair of 45s is 45. This is the convention most lifters use, it is what people mean when they say they pressed the 30s, and it is what the voice model expects when you say it out loud. Choose it now and never change it. If you already have a notebook with the other convention, that is fine too; the rule is not per hand, the rule is one way forever.
3. Decide what a warm-up is
Log any warm-up set that carries real weight, because it is work and it shows how you built up to the top set. The empty bar and the mobility drills can be left out. Draw the line wherever you like, then leave it there, so the number of sets on a day means the same thing in March as it did in January. The training volume tool will show you how much those warm-up sets add across a week, which is usually more than people expect and a good reason to keep them in.
4. Log between sets, not afterwards
Every set, while the number is still true. A set logged that evening from memory is a set with the weight rounded up and one rep added, and the difference compounds. This is why the entry has to cost seconds. Say it into the mic, "dumbbell press, three sets of ten at twenty," and voice logging turns the sentence into three lines you review before saving. Or tap it in on the keypad with last session's numbers already on the screen. How to log workouts with your voice on iPhone walks through the phrasing if you want to see what one sentence covers.
5. Keep exercise names consistent
Every set you want compared has to land under the same exercise name. Incline dumbbell press and flat dumbbell press are two entries. Squat and goblet squat are two entries. A notebook makes you remember which name you used last time; a catalog does it for you, and the voice model prefers exercises you have trained recently when a name is ambiguous, so "presses" lands where it landed last week.
6. Compare, then add
Before each set, look at last session's line. That is the whole reason the log exists. If every rep felt smooth last time, add the smallest step your gym allows: a rep, 2.5 kg on a bar, the next dumbbell up. If it did not, repeat. You do not need a column for how it felt to make that decision, because the decision is written into the next line. When a set beats your history, Strongbro records it as a personal record automatically, and the Records screen shows the best set per exercise per month, so the growth you were told to look for is visible without you formatting anything.
That is the whole log. Three numbers a set, three conventions fixed once, and the app applying them the same way every session. If you want to see what a month of it looks like on one page, a simple workout log shows the layout in full.
What this is based on
The principle that progress comes from small, measured increases against a known baseline follows the ACSM position stand on progression models in resistance training, and the NSCA's education material covers the same idea for beginners. The NHS and CDC pages on strength training set the two-days-a-week floor that any log should show you clearing. None of this is medical advice; if a lift hurts, stop and talk to a clinician.
Setup checklist
- Log one line per set: exercise, weight, reps, nothing else required
- Decide dumbbells per hand, and apply it to every dumbbell lift from now on
- Log warm-up sets that carry real weight; skip the empty bar if you like
- Leave feel and effort out until month two
- Log during the session, between sets, not from memory at night
- Name each exercise the same way every time so history stays under one entry
- Read last week's line before starting this week's set

Frequently asked questions
Do I write 45 or 90 for a pair of 45 lb dumbbells?
Either works, as long as you never switch. Per hand is the convention most lifters use, so a pair of 45s is logged as 45, and it is what people mean when they say they benched the 45s. The only wrong answer is 45 one week and 90 the next, because then the two lines cannot be compared and the log has stopped doing its job.
Should I log warm-up sets?
Log the ones that carry real weight, because they are work and they show how you built up to the top set. The empty bar and mobility work can be left out. Whatever you decide, keep the rule fixed, so the number of sets on a page means the same thing in March as it did in January.
Do I need to write how the set felt?
Not yet. Effort ratings are useful once you have a month of numbers to compare them against; before that they are one more thing to decide between sets, which is exactly what stalls beginners. Start with weight and reps. Add an effort scale in month two if you find you want it.
Is one line per exercise enough, or one per set?
One per set. Three sets of eight at 60 kg can be written on one line as shorthand, but the sets rarely stay identical for long, and the moment a third set drops to six reps you want that difference on record. A tracker logs each set separately by default, which removes the decision entirely.
What if I forget to log during the session?
Add it as soon as you can, with the correct date. Memory rounds weights up and forgets sets, so a same-day entry is better than a next-day one, and a next-day one is better than nothing. In Strongbro the date pill in the keypad lets you log yesterday's session with the same taps as today's, and records carry the date the set was actually done.
How do I know whether I am making progress?
Lay this week's line next to the same exercise from last week. More weight at the same reps, or more reps at the same weight, is progress; the same numbers held is a normal week, not a failure. Over a month those small steps become a visible line, and a tracker will show the best set per month so the climb reads at a glance.
