Build it with AI

Build a workout planner you will actually open

A training log only works if opening it takes less effort than skipping it. This guide covers building a small single-file log that matches your equipment, your available days and the lifts you actually do. It is an organisation tool: it records what you did and shows you the pattern. It does not design your programme, judge your form or tell you whether an exercise is safe for you - those are decisions for you and a qualified professional.

The 15-second walkthrough for this guide has not been published yet. The written tutorial below is complete and stands on its own — the video repeats it, it does not replace it.

The full narration is in the script section.

What you start with

The equipment you have
Adjustable dumbbells up to 25kg, a bench, a pull-up bar, and no barbell or rack.
The schedule you can keep
Three sessions a week of about 45 minutes, usually Monday, Wednesday and Saturday morning.
What you want to see
Each session's exercises, sets, reps and load, plus a plain-language note field for how the session felt.

Handling sensitive information

Training logs are health-adjacent personal data. Keeping the data in your own browser rather than a third-party account is the safer default, but it also means no backup - export it periodically. Do not paste medical history, diagnoses or clinical notes into a general-purpose AI tool while building the app; describe the tool, not your health record.

The process, step by step

  1. Step 1

    Start from your constraints, not an ideal programme

    List the equipment you own, the days you can realistically train and the movements you already perform confidently. A log built around equipment you do not have is abandoned in week two.

  2. Step 2

    Ask for a log, not a coach

    Specify that the app records sessions and shows history. Do not ask a model to prescribe loads, progressions or rehabilitation - that is a coaching decision that depends on your history and how you move, which no text tool can observe.

  3. Step 3

    Optimise for the thirty seconds between sets

    Entering a set should take a couple of taps. Ask for large touch targets, sensible defaults from the previous session, and no required fields beyond the exercise and the numbers.

  4. Step 4

    Review the pattern weekly, not the app

    Once a week look at what you actually completed versus what you planned. That gap is the useful output. Adjust the plan to fit your life, and take questions about programming or pain to a qualified professional.

How to review the result

  • Can you log a full set in under ten seconds with one hand?
  • Does the history survive a reload, and can you export it as plain text?
  • Does the app avoid suggesting weights, intensities or progressions on its own?
  • Is there a free-text field for how a session felt, including any discomfort you want to raise with a professional later?
  • Does it work offline, in a gym with no signal?

Limits and boundaries

  • This is a general planning and record-keeping aid. It is not medical care, not physiotherapy, and not a substitute for a qualified coach or clinician.
  • It cannot see your technique, your injury history or how you move, so it cannot judge whether an exercise is appropriate for you.
  • Stop the exercise and seek advice from a qualified professional for sharp or radiating pain, joint pain, dizziness, or pain that changes how you move. Normal muscle fatigue is different from pain, and only you and a professional can tell them apart in person.
  • No app can promise strength, weight or physique outcomes. It records what you did; it does not guarantee a result.
  • If you have an existing injury or condition, are pregnant, or are returning after a long break, get clearance from a doctor before starting a new training routine.

How AI was used to make this page

This page and the 15-second video script were drafted with AI assistance and then edited and fact-checked by a human before publication. The training log described here was built from the sample requirements on this page, and nothing on this page was written or reviewed by a medical professional.

Each one is a one-time purchase with lifetime access.
