How to log your workouts in under a minute

A training log has exactly one job: to tell you next week whether you did more than last time. Everything about how to keep one follows from that.

Why memory is not sufficient

People consistently believe they remember what they lifted. They do not.

The specific failure is not forgetting a number entirely; it is remembering it generously. Last week's set of eight becomes "eight or nine", and the week after that it becomes "about the same". Over a couple of months, "a bit more than before" drifts into repeating the same session indefinitely.

This is the most common reason someone trains consistently for a year and looks unchanged. Not a bad programme — no progressive overload, because nobody was measuring.

What to record

Four things, and a fifth when there is something to say.

The exercise. By name, consistently. "Incline dumbbell press" every time, not sometimes "incline press".

The weight. As it was on the bar or the dumbbell.

The repetitions. Actual, not planned. A set of five that became four is a four.

How hard it was. One digit: reps in reserve, or an RPE score. This is the field people skip and it carries more information than any other, because 60 kg for eight easy and 60 kg for eight barely are different sessions that look identical in a log without it. The scales are explained in RPE and RIR: how to rate a set you just did.

A note, when warranted. "Left shoulder tight." "Rushed, poor sleep." "Form broke on the last two." Three words, occasionally, not an essay.

A complete entry looks like: Squat — 100 kg × 5 @ 2 RIR.

What to skip

Calories burned. Wildly inaccurate and it encourages treating training as a way to earn food, which is a bad relationship with both. See are the calories-burned numbers worth anything.

Heart rate, for lifting. Interesting and not actionable for strength work.

Rest times, usually. Worth recording during a specific phase where density is the variable, otherwise noise. Covered in how long to rest between sets, by goal.

Total tonnage. Sets times reps times weight looks scientific and rewards doing light weights for many repetitions. Hard sets per muscle per week is the more useful volume measure — training volume or intensity: what to track.

How you felt, in paragraphs. A one-word note is useful. A journal entry is a different activity.

Log during the session

In the rest between sets, while sitting down. It takes a few seconds per set and you were not doing anything else.

Logging afterwards from memory produces the same drift described above, plus it is slower, because you are reconstructing rather than recording.

The practical test of a logging tool is whether it shows you last week's numbers for the exercise you are about to do, without searching. If it does, logging takes seconds. If it does not, you will stop.

Reading it

The weekly question is narrow: compared with last time, did the weight go up, the reps go up, or the rating get easier at the same numbers? Any of those three is progress.

The monthly question is broader: is the trend across four to six weeks upward? Individual sessions vary with sleep, food and stress by more than most people expect, which is why session-to-session comparison produces false alarms. The method is in how to read real progress out of a training log.

What a log makes possible

Deliberate overload. You can add load on purpose rather than by accident, which is the whole subject of progressive overload, in numbers you can check.

Volume management. Counting hard sets per muscle per week takes a minute from a log and is impossible from memory — how many sets per muscle per week is enough.

Early warning. Performance falling across several sessions is visible in a log before it is felt, which is how you catch the need for a deload before it becomes an injury. See deload weeks: when you need one and how to tell.

Diagnosis. When progress stops, the log tells you whether you actually trained the thing that stopped progressing. Usually the answer is surprising.

A worked week

What a real log looks like for someone training four days, kept in the rest periods and taking under a minute per session.

Monday, lower. Squat 100×5 @2, 100×5 @2, 100×5 @1. Romanian deadlift 80×8 @2, 80×8 @2. Leg press 160×12 @2, 160×12 @1. Calf raise 60×15 @1, 60×15 @0.

Tuesday, upper. Bench 75×6 @2, 75×6 @2, 75×5 @1. Row 70×8 @2 ×3. Overhead press 45×8 @2 ×2. Curl 15×12 @1 ×2. Note: "left shoulder tight on press".

Next Monday the decision is made in three seconds: the third squat set was at 1 RIR, so repeat 100 kg and aim for 5, 5, 5 at 2 RIR, or move to 102.5 if all three felt like 2. That decision is impossible without the ratings and trivial with them.

What the log is not for

It is not a record of effort or virtue. A session where you felt destroyed but lifted less than last week is a worse session, and a log that says so is doing its job.

It is also not a place to record everything you could measure. Fields you fill in inconsistently invite conclusions the data cannot support, which is why the list of things to skip is as important as the list of things to record — set out in what to record in a training log, and what to skip.

Notebook or app

A notebook works. It has produced a great many strong people and it never runs out of battery.

An app earns its place by doing arithmetic you would not do by hand: estimating your maximum from a set of five, summing weekly sets per muscle, plotting six months of a lift. And by showing last week's numbers instantly, which is what makes logging fast enough to sustain. The comparison is in notebook or app: what a workout log is really for.

Why it belongs with your food log

Training and eating are one project. Whether you are gaining strength on a given calorie intake, whether a deficit is costing you performance, whether a bad week of sleep shows up in both — these questions need both records in the same place.

Keeping them in two apps means never asking them, which is the argument in why food and training belong in the same log.

Start today

Write down what you lift today, with the four fields. Next session, beat one number. That is the entire method, and everything else on this site about training is a refinement of it.
