What to log in every workout, what to skip, and how to turn your training notes into clear, simple decisions about when to add weight, add reps, or back off.
For each working set, log four things: the exercise, the weight, the reps, and how hard it felt (ideally as reps in reserve). That is enough to apply progressive overload, spot plateaus, and decide when to deload. Skip warm-ups, exact rest times, and detailed notes unless they change a decision. Review your log before each session so you know what to beat.
Most people who stop progressing in the gym are not lazy. They simply cannot remember what they did last time. Without a record, every session becomes a guess, and guesses drift toward whatever feels comfortable.
A workout log fixes that. It does not need to be elaborate. A few numbers per set, written down consistently, are enough to tell you what to do next.
Progressive overload means doing a little more over time: more weight, more reps, or more sets. You cannot do more than last time if you do not know what last time was.
The American College of Sports Medicine's 2009 position stand on progression models recommends increasing the load by about 2 to 10% once you can exceed your target reps by one or two on two consecutive sessions. That rule only works if you have written down your reps.
A log also helps you:
Keep it to the essentials. For each working set:
Here is what that looks like:
| Exercise | Weight | Reps | RIR |
|---|---|---|---|
| Back squat | 225 lb | 6 | 2 |
| Back squat | 225 lb | 6 | 2 |
| Back squat | 225 lb | 5 | 1 |
| Romanian deadlift | 185 lb | 10 | 3 |
That is the whole job. Everything else is optional.
Weight and reps tell you what happened. Effort tells you whether you could have done more.
Two sessions of bench at 185 × 8 can mean very different things. If the first was a grind with nothing left and the second had two reps in the tank, you got stronger, even though the numbers on paper are identical.
The reps-in-reserve scale is the most practical way to capture this. Zourdos and colleagues introduced an RIR-based version of the RPE scale in 2016, and found that experienced lifters rated their effort more accurately than novices, particularly on heavy sets. Helms and colleagues then laid out how to use RIR in program design to adjust loads from session to session.
A simple scale works fine:
| How it felt | Approximate RIR |
|---|---|
| Very easy | 4 or more |
| Easy | 3 |
| Moderate | 2 |
| Hard | 1 |
| Max effort | 0 |
You will not be perfectly accurate at first. That is fine. Ratings get better with practice, and even rough ratings beat none.
Every extra field is friction, and friction is what makes people stop logging. Leave these out unless they actually change a decision for you:
A log is only useful if it changes what you do. A simple decision rule, often called double progression, works for most exercises:
Plotkin and colleagues compared adding load against adding reps in a 2022 study and found similar muscle growth with both. Double progression uses both, so you always have a next step.
A worked example from a log, bench press, 3 sets, 6 to 10 reps:
| Session | Weight | Reps | Last set RIR | Next step |
|---|---|---|---|---|
| 1 | 185 lb | 8, 8, 7 | 1 | Add a rep |
| 2 | 185 lb | 9, 9, 8 | 1 | Add a rep |
| 3 | 185 lb | 10, 10, 10 | 1 | Add weight |
| 4 | 190 lb | 7, 7, 6 | 2 | Add a rep |
Without the log, session 4 might have been a guess. With it, the next step is obvious.
Two short habits do most of the work:
If a lift has stalled for three sessions, change something small, such as dropping the weight about 10% and building back up. If many lifts slip together, consider a deload week.
Alexandros is an iPhone app that works like a personal weightlifting coach you talk to in a chat. The biggest reason people stop tracking is that it is tedious, so it lets you log the way you would text a friend: "leg press, 4 sets of 12 at 300, felt easy" or "db bench 4x10 with the 50s, last set was a grind". It turns that into structured sets and shows a workout card where you can tap to fix any line. You can also tap sets in manually.
Every set gets an effort rating on the five-point scale above, or you can give reps in reserve directly. From there it applies double progression for you, within a rep range set by your goal and the type of lift. You can ask "How has my squat progressed?" and get charts of top weight, estimated 1RM, and volume. Every number in a reply comes from your actual log, so it never invents weights.
Yes, if you use it consistently. A notes app, a paper notebook, or a spreadsheet all work. What matters is logging weight, reps, and effort for every working set and checking it before your next session.
Usually not. Warm-ups are there to prepare you, not to drive progress. If you want a record, a quick note like "worked up to 185" is plenty.
Roughly accurate is fine. The goal is to tell an easy set from a hard one. Research suggests ratings get more accurate with experience and on heavier sets, so expect to improve over time.
Pick up where you left off. If you missed more than a week or two, start a little lighter, around 5 to 10% below your last weights, and build back up over a few sessions.
