To track workout progress, log five things for every set: the exercise, the weight, the reps, how many sets you did, and how hard it felt (RPE, on a 1–10 scale). Then, before your next session, use one simple rule to decide whether to add weight, keep it the same, or back off. The log is only half the job. The decision you make from it is what drives progress.
Most guides to tracking workouts stop at the first half. They tell you to write things down and “look for trends”, and leave you staring at three months of numbers with no idea what they mean. This guide covers both halves: what to record, which numbers show real progress, and how to turn last week's log into this week's plan.
Training by feel works for a few weeks. After that, memory fails you. You remember that you squatted “around 90” last week, but not whether that was 3×5 or 3×4, or whether the last set was easy or a grind. Those details decide what you should do today.
Muscles and strength grow when training asks for a little more than it did before. That principle is called progressive overload, and you can't apply it without a baseline. “A little more than last time” only means something if you know what last time was.
A log also protects you from two opposite mistakes:
Tracking doesn't need to be elaborate. It just needs to be consistent enough that next week you can see exactly what you did this week.
If you're wondering how to log workouts without it taking over your session, the answer is to log a small, fixed set of fields every time. A consistent short log is far more useful than a detailed one you keep half the time.
These four fields are the minimum. Here's what one exercise looks like in a good log:
| Exercise | Set | Weight | Reps | RPE |
|---|---|---|---|---|
| Back squat | 1 | 80 kg | 5 | 6 |
| Back squat | 2 | 80 kg | 5 | 7 |
| Back squat | 3 | 80 kg | 5 | 8 |
Two small habits make this much more useful later:
Warm-up sets are optional. Most lifters skip them, because they don't reflect working capacity.
RPE stands for rate of perceived exertion. It's a 1–10 score for how hard a set was. In lifting, it's usually tied to how many more reps you could have done:
| RPE | What it means |
|---|---|
| 10 | Max effort. No more reps possible |
| 9 | 1 rep left in the tank |
| 8 | 2 reps left |
| 7 | 3 reps left. Bar speed still good |
| 6 or below | Comfortable, 4+ reps left |
This “reps left” version was set out by Zourdos and colleagues in 2016 and is now the standard way lifters use it (Zourdos 2016). The “reps left” number has its own name, RIR (reps in reserve). For the full breakdown, including how RPE maps to a percentage of your max, see our RPE chart, or the short definitions of RPE and RIR.
Why it matters: RPE is the field that tells two identical-looking sessions apart. “80 kg × 5 at RPE 6” and “80 kg × 5 at RPE 9” have the same weight, the same reps and the same volume. But the first means you're ready to add weight, and the second means you're at your limit. Without RPE, your log can't tell them apart.
If RPE feels abstract at first, that's normal. Beginners tend to rate sets as harder than they are. Your scores get more accurate within a few weeks of practice, and even rough scores are far more useful than none.
You don't need to log rest time for every set. But keep it roughly consistent for each exercise, and note it if it changes. Three sets of 5 with 3 minutes' rest isn't the same workout as three sets of 5 with 90 seconds. A rest timer makes this automatic. Research generally favours longer rest (2–3 minutes or more) on heavy compound lifts for both strength and muscle growth. In one study of trained men, 3 minutes' rest beat 1 minute on both (Schoenfeld 2016). For the details, see how long to rest between sets.
A short note explains the outliers when you look back:
You don't need a diary. “Slept 5 hours” next to a bad session saves you from wondering later whether you've plateaued.
The honest answer is that the best tool is the one you'll use every session. A notebook that goes to every workout beats an app you abandon. That said, each option has real trade-offs:
| Notebook | Spreadsheet | Workout app | |
|---|---|---|---|
| Logging mid-set | Fast, but sweaty pages | Slow on a phone | Fast, with last session's numbers pre-filled |
| Seeing last session | Flip back pages | Scroll or filter | Shown automatically |
| Spotting trends | Hard | Possible with formulas | Charts built in |
| Setup effort | None | Build it yourself | Install and pick exercises |
| Survives years | Fills up, gets lost | Yes | Yes, if it syncs |
A notebook is a perfectly good way to start. The weakness shows up later: after a few months you have plenty of data but no easy way to see a trend in it. That's the main reason most lifters eventually move to an app. We compare the two in more detail in workout journal vs app.

Once you've logged a few weeks, the question changes from “what did I do?” to “am I improving?”. Four numbers answer that better than scanning raw sets.
Your weights and reps change from week to week, so comparing raw sets is messy. Is 80 kg × 8 better than 90 kg × 5? An estimated one-rep max (e1RM) converts any set into a single comparable number. The most common formula is Epley's (Epley 1985):
e1RM = weight × (1 + reps ÷ 30)
So 100 kg × 5 gives an estimated max of 100 × (1 + 5/30) ≈ 117 kg. Plot your best e1RM per session for each main lift, and you have a strength trend line that works even when your rep ranges change. The estimate is least accurate at high reps, so treat sets above about 10 reps as a rough guide. More in the glossary entry on one rep max.
Volume is the total work you did: sets × reps × weight. Three sets of 8 at 80 kg is 3 × 8 × 80 = 1,920 kg. Rising volume at a similar effort level means you're doing more work than before, which counts as progress even when your top weight hasn't moved.
For muscle growth, it also helps to count hard sets per muscle group per week. Research suggests more weekly sets generally produce more growth, up to a point, with around 10 or more hard sets per muscle per week working well for most people (Schoenfeld 2017). For how to set your own number, see how many sets per muscle group per week and our definition of training volume.
Average RPE per session is your fatigue gauge. If your weights are flat but your average RPE is falling, you're getting stronger, and it's time to add load. If your weights are flat and your average RPE is climbing, fatigue is building faster than you're recovering. Watch that pattern over two or three sessions, not one.
Personal records (PRs) are the most motivating number in your log. Count more than one kind:
Many people think they've stalled because their top weight hasn't moved in a month. Then they look at their log and find a rep PR or a volume PR almost every week. That's progress, and tracking is how you see it.
This is the part most tracking advice leaves out. A log that you only read is a diary. A log that decides your next session is a training tool.
Here's a rule you can apply to each exercise after every session. It uses the RPE you logged:
| Average RPE this session | What happened last session | Next session |
|---|---|---|
| 7 or lower | Anything | Add weight (2.5 kg on most lifts) |
| Above 7 | Averaged below 8 | Keep the same weight |
| Above 7 | Also averaged 8 or higher | Drop to about 80% and build back up |
This is the rule Sweatora uses to suggest your next session's weights. For bodyweight exercises, it works the same way on reps. It isn't the only valid rule, but it has three properties that any good rule needs:
The exact numbers matter less than having a rule and deciding it before the session. Mid-set, fatigue and ego make bad decisions.
Adding 2.5 kg every session stops working eventually, especially on smaller lifts like curls or lateral raises, where 2.5 kg can be a 20% jump. The standard fix is to progress reps first and weight second. Work in a rep range, say 8–12. Add reps each session until you hit 12 on every set, then add weight and drop back to 8. That's the double progression method, and a log makes it almost automatic: you just check whether last session hit the top of the range.
If an exercise has been flat for three or more sessions, with no weight, rep or volume PR and RPE stuck high, your log has found a plateau. Before changing your program, check the notes column. Sleep, stress and missed sessions explain more stalls than bad programming does.
If the stall is real, you have two main tools. The first is a deload week: a planned lighter week that lets fatigue clear, so the strength you've built can show. The second is changing a variable, like the rep range, the exercise variation or the weekly sets. Our guide on how to break a strength plateau covers both in detail.
Adjusting training day to day based on how you're performing is called autoregulation. The RPE rule above is a simple form of it.
Once a week, spend ten minutes on your log. Not every day: daily numbers are mostly noise. For each main lift:
Monthly, zoom out: body weight trend, total sessions completed, and whether your weekly sets per muscle group match what you meant to do.
Sweatora is built around the second half of this guide. You log sets, reps and weight as you train, rate each set with one tap (Easy, Good, Hard or Max, recorded as RPE 5, 7, 8 and 10), and a rest timer runs between sets. After each session, it applies the decision rule above to every exercise and suggests next session's weights. Its stats screen tracks estimated 1RM, volume per session, best sets, average RPE over time, and weight and volume PRs, so the weekly review takes minutes. A workout streak and body-weight check-in reminders cover the consistency side. We wrote about why consistency matters separately.

Glance at last session's numbers before each workout, so you know today's targets. Do a proper review once a week, and zoom out once a month. Reviewing every day mostly shows you noise, like sleep, food and stress, rather than real changes in strength.
No. Warm-ups don't reflect your working capacity, and including them skews your volume numbers. Log your working sets only. If you use a structured warm-up, a one-line note like “standard warm-up” is enough.
Not at first. Most beginners overrate how hard a set was. It gets better quickly with practice, especially if you sometimes check a rating by doing one more rep on a safe exercise. Even rough RPE scores are more useful than none, because what matters is the trend across sessions.
Keep the same exercise names and your history carries straight over. Your estimated 1RM and PRs still compare across programs. Expect a short dip when rep ranges change. That's the new program, not lost strength.
