Logging basics

What to record in a workout log

The five details that make a workout log useful, plus a worked example for recording sets without turning your session into admin.

The short answer

Record the date, exercise, weight, and reps for each set. Add a short note when something changes how you should interpret the numbers.

Start with a record you can repeat

A useful workout log answers a small question: what did I actually do last time? It does not need to capture everything you felt or every minute you spent in the gym. It needs enough detail to make the next session easier to understand.

For strength workouts, keep the date, the exercise name, and the weight and reps for each set. Recording each set separately preserves details that a session total loses. Three sets of eight and three sets of ten are different records, even when both get remembered as ‘three sets of bench.’

  • Date: when the session happened, especially if you enter it later.
  • Exercise: a consistent name, including a meaningful variation.
  • Weight and unit: 60 kg and 60 lb are very different entries.
  • Reps per set: record what you completed, not just what you planned.
  • Context: a brief note when equipment, setup, or execution changed.

Write the actual sets

Suppose you planned three sets of eight on the bench press, but completed eight, eight, and six. Log those numbers. Rounding the last set up to the plan makes the record less useful when you return to it.

Make your weight convention explicit. For a barbell, record the total load including the bar. For dumbbells, specify whether the number is per hand, then use that convention consistently.

Example workout entry
September 17
Barbell bench press — total load
60 kg × 8
60 kg × 8
60 kg × 6
Note: last set paused; first two touch-and-go.

Use notes to explain the unusual

Notes are most valuable when a number needs context. A different machine, a changed bench angle, or a longer pause can make an exercise harder to compare with last week. ‘Different cable station today’ is more useful than a paragraph that you will never read again.

You can also record effort if it helps you interpret a set. Keep the wording consistent and remember that effort is a personal estimate. It supplements the weight and reps; it does not replace them.

Warm-up sets can live in the same log, but label them. That keeps you from confusing preparation sets with the working sets you intended to compare.

Make the log useful next time

Before repeating an exercise, pull up the previous entry and check the variation, load, and completed reps. After the session, record the new result in the same format. Consistency in naming and units matters more than elaborate formatting.

Rudy lets you text your sets from Messages and review them in a web dashboard. Whether you use Rudy, paper, or a spreadsheet, the goal is the same: leave your next session a clear record instead of a memory test.
