How to Keep a Training Log for Strength Training

If you write down your training, you know where to start next time – and after a few weeks you can see whether you are really making progress. A training log is one of the simplest and most effective tools in strength training.

Why a training log is worth it

• A clear target for the next session: You know the weight and reps you managed last time and can plan a specific step up instead of guessing.
• Progress becomes visible: Single sessions often feel alike. Only the numbers over several weeks show how you are developing.
• You spot stalls early: If an exercise does not move for a long time, you see it in black and white and can review training, recovery or technique.
• You keep the overview: Which muscle groups do you train often, which rarely? Without records this hardly shows.

What to record

Less is more: what matters is that you really record it every time. These fields have proven useful:

• Date of the session
• Exercise (always under the same name)
• Weight per set
• Reps per set
• Number of sets
• Optional: rest time, effort (how many more reps could you have done?) and short notes on sleep, pain or technique

An example

Bench press, three sets: 60 kg × 8, 60 kg × 8, 60 kg × 7. Next time the goal is 60 kg again with 8 reps in every set. Once that works, you increase the weight slightly in the following session. That turns the log into a concrete plan for the next workout.

Common mistakes

• Recording too much at once: If you try to capture every detail, you give up quickly. Start with exercise, weight and reps.
• Inconsistent exercise names: “Bench press”, “flat bench” and “bench” count as three different exercises in any analysis.
• Only logging the weight: Without reps you cannot compare progress.
• Never reviewing it: A log only helps if you look at it regularly – for example before every session and once a month for a review.

How to get started in five minutes

1. Decide where you write things down – notebook, notes app or tracker – and stick with it.
2. Before the session, write down what you plan to do, based on last time’s numbers.
3. Log each set right after you finish it, not in the evening. Otherwise details get lost.
4. Add a short note at the end: how did the session feel?
5. Before the next session, glance at your last numbers.

What to look at when reviewing

Do not judge single days. One day you are tired, the next you feel great. The trend over three to four weeks is more telling: if weight or reps on your key exercises rise slightly, you are on a good track. If a number stays put for longer, check sleep, nutrition and technique – and note what you change so you can see the effect later.

Personal records help as well. If you know your heaviest weight for a given rep count on each exercise, you immediately see whether today’s training is better or worse than usual.

Paper, spreadsheet or app?

A notebook is quick to set up and needs no battery, but offers no analysis. A spreadsheet is flexible but has to be maintained and evaluated by hand. A training app shows your last values while you log, calculates progress and personal records automatically and points out muscle groups that are falling behind. In the end, what matters is what you will actually keep using.
