Plan the process by setting the repetitions and optional rest time for the next set, performing the set, and pressing Complete set only after you finish.
The Workout Rep Counter is built for that narrow job: it saves each completed set in your browser, shows today’s set and repetition totals, starts a countdown when requested, and lets you export a dated record. It does not generate an exercise plan, so your own plan should identify the movements and set order while the counter handles the numbers you enter after each set.
Plan Your Workout Rep Counter Session
- Decide the set sequence before you begin. Write down the movements, intended order, and target repetitions in your own notes. The counter records completed sets; it does not prescribe exercises, set counts, training volume, or recovery intervals.
- Enter the repetitions for the next set. Use a whole number from 1 through 1,000. The value comes from your plan, and the tool does not judge whether it is appropriate for you.
- Add an optional rest duration. Enter a value from 0 through 3,600 seconds. Zero means no rest countdown is needed, while any positive value can start a local countdown after you complete the set.
- Perform the planned set. Follow the instructions for the movement you chose. The tool does not use a camera, microphone, or movement detector, so you must enter the repetition count yourself.
- Press Complete set after finishing. The page saves one completed set, increases today’s set count, and adds the selected repetitions to today’s rep total. If you requested rest time, the countdown can start at this point.
- Use the countdown as a simple readiness prompt. Press Skip rest when you are ready to clear it and continue. With a rest duration of zero, there is no countdown to manage.
- Check the inputs before each later set. Update the reps or rest duration when your plan changes. Each completed set retains the number used when it was recorded, and the last selected values remain available for the next interaction, so review them rather than assuming they still match.
- Correct, review, and export when appropriate. Use Undo set for a mistaken completion. After the session, review Daily history, and export PNG or CSV only when you want a copy outside the browser.
Choose the Inputs Before Each Set
A reliable workflow keeps three things separate: the exercise you intend to perform, the values you enter, and the action that saves the result. The counter accepts only specific values, so decide the rep count and rest duration before pressing the completion control.
| Control or action | Accepted input or behavior | Recorded result |
|---|---|---|
| Reps per set | A whole number from 1 through 1,000 | The value is used when the set is completed and remains attached to that saved set. |
| Rest duration | 0 through 3,600 seconds | Completing the set can start the requested countdown; zero means no countdown. |
| Complete set | Press after finishing the set | One set is saved, and today’s set and rep totals are updated. |
| Undo set | Press when the latest completed set was a mistake | The most recently completed set is removed from that day, and its totals are recalculated. |
Sets and repetitions remain distinct in the record. The set total shows how many sets were completed, while the rep total reflects the repetition values entered for those sets. Neither total is a training-volume recommendation; both are personal entries.
Use the Rest Timer Only as a Prompt
The rest timer is deliberately narrow. It starts from the duration you entered and runs as a local convenience after a completed set. It does not assess whether a recovery period is long enough, detect when you are physiologically ready, or recommend a different interval.
Choose zero when you do not want a countdown, such as when the next movement follows immediately. When a countdown is active, use Skip rest to clear it early. This keeps the timer tied to your own sequence without turning it into medical guidance or an automatic training decision.
Correct the Latest Entry and Review Totals
If you press Complete set before the set is finished or enter the wrong count, use Undo set immediately. It removes the most recently completed set from the current calendar day and recalculates that day’s totals. You do not need to clear the entire history to reverse one mistaken entry. For a focused walkthrough, see how to fix a wrong result in Workout Rep Counter.
Afterward, open Daily history to review each saved date. Every row shows the number of completed sets and the total repetitions recorded for that date. The day is calculated from your device’s local timezone, so a late workout remains attached to the local day on which you recorded it rather than being moved by a UTC date boundary.
Daily totals are useful for checking your entries, but they do not verify that the workout happened exactly as planned. If a set was entered incorrectly, correct it before relying on the row. Once it is saved with the intended rep value, later changes to the input box do not rewrite that earlier set.
Match the Export to the Record You Need
Exporting is optional because the history already remains available in the browser. Choose the format based on how you plan to review or share the record.
| Output | What it contains | Practical use |
|---|---|---|
| Daily history | Each saved date with its completed-set count and total repetitions | Checking the dated log without leaving the counter |
| CSV export | One row per saved day with Date, Sets, and Reps columns | Opening the history in a spreadsheet for review |
| PNG export | A 1080 by 1350 image with the Lizely mark, a total, and recent day rows | Creating a visual summary; it does not include a URL or a custom workout label |
Both file exports are generated in the browser through native canvas and Blob APIs. Export them when you want a separate copy, then keep the CSV for row-by-row spreadsheet data or the PNG for an image summary. The exports do not turn the tool into a cloud database or add an account-based backup.
Account for Local Storage and Privacy
Each completed set is stored as a user-entered whole number in browser local storage, the mechanism covered by the WHATWG Web Storage specification. The tool has no account, synchronization service, tracker, hidden upload, or API request for completed sets. Your stored history belongs to that browser rather than to a profile.
That design has practical consequences. Clearing browser data removes the history, and another device begins with an independent, empty record. If local browser storage is unavailable, the page still shows the interaction currently open but reports that it cannot save a durable history. Plan to export a copy before clearing browser data if you need the record to remain available.
For routine use, open the counter in the same browser where you want its history kept. Local storage is not a substitute for scheduled exports, especially when using temporary browser sessions or moving between devices.
Keep the Tool’s Scope Clear
The counter is a lightweight record of decisions you make, not a workout planner or an automatic rep detector. It does not detect movement, infer form, estimate calories, measure your body, prescribe a recovery interval, or make a health claim. The values entered for reps and rest are your own record rather than recommendations generated by the tool.
A sound plan therefore depends on three separate actions: prepare the exercise sequence yourself, enter the correct set values before completion, and review the saved history afterward. Once those steps are clear, Complete set, Undo set, and the two export formats provide a focused way to record each workout without account setup.
