Use Workout Rep Counter correctly by setting the repetitions and optional rest duration before a set, pressing “Complete set” only after the set is finished, and using “Undo set” to remove the latest mistaken entry. The Workout Rep Counter is a manual workout log rather than a camera-based rep detector: you provide the rep count, and the page saves the completed set, updates today’s totals, and starts a rest countdown when you requested one. That sequence helps keep the record aligned with what you actually performed, but the tool does not block a premature press of Complete set; use Undo set to remove an accidental latest entry. Correct use also means checking the saved set count separately from the total repetition count, understanding that a rest timer is only a local prompt, and exporting a copy if you want a record outside the browser. It does not mean using the tool to prescribe training volume, judge exercise form, estimate calories, or make a health recommendation; those functions are outside its purpose.
The Accuracy Rule: Configure, Complete, Then Verify
The counter is accurate only when its inputs reflect the set you intend to record. Its operating rule is straightforward: configure the next set, complete it after the work is finished, and then verify the totals. This avoids recording an intended set as completed or accidentally saving a stale rep value from an earlier set.
| Control or field | Accepted value or action | What it does | When to use it |
|---|---|---|---|
| Reps per set | Whole number from 1 through 1,000 | Sets the rep value used for the next completed set | Before pressing Complete set |
| Rest duration | 0 through 3,600 seconds | Sets the optional local countdown | Before pressing Complete set |
| Complete set | Press the button | Saves one completed set and updates today’s set and rep totals | Only after finishing the set |
| Undo set | Press the button | Removes the most recently completed set from the current calendar day and recalculates the totals | When the latest entry is wrong |
| Skip rest | Press the button | Clears the active rest countdown | When you are ready to continue |
The selected reps and rest duration remain available for the next interaction, while each saved set keeps the repetition number used when it was recorded. That distinction prevents a later input change from rewriting an earlier set: if you change Reps per set before the next completion, the previous set still reflects its original entry.
Match the Inputs to the Set You Are About to Perform
Enter the whole-number rep total that matches the set you plan to mark as completed. The accepted range is 1 through 1,000. If you decide to perform a different number, update Reps per set before pressing Complete set. The tool cannot observe how many movements you performed, so it cannot correct an inaccurate entry automatically.
Rest is optional, but its accepted range is 0 through 3,600 seconds. Choosing zero keeps the counter available for circuits or other sessions where a countdown is not wanted. These inputs are personal record values rather than training advice: the tool does not imply that a particular number of reps or rest seconds is appropriate for you.
Run the Record-and-Verify Routine
- Open the Workout Rep Counter before beginning your set. No account or sign-up is required.
- Enter the number of repetitions for the next set in Reps per set. Confirm that it is a whole number from 1 through 1,000 and that it represents the set you intend to record.
- Choose an optional rest duration from 0 through 3,600 seconds. Leave the countdown out by entering zero if you do not want one.
- Perform the set. The counter remains a manual log during the exercise; it does not use the camera, microphone, movement detection, or an AI model to count repetitions.
- Press Complete set after the set is finished. The page saves the set, adds it to today’s completed-set and repetition totals, and starts the countdown if you requested a rest duration.
- Use Skip rest to clear the countdown when you are ready to move on. Skipping the countdown does not remove the completed set from your record.
- Check today’s set and rep totals before continuing. Before the next set, update Reps per set or the rest duration if the retained selection no longer matches what you need.
- If the most recent completion was a mistake, press Undo set. The latest set is removed from the current calendar day and the totals are recalculated, so you do not need to clear the entire history.
- Review the Daily history list when you finish. Export the dated records as CSV or PNG if you want a copy outside the browser.
Separate Sets from Repetitions in the Daily Record
Completed sets and total repetitions are separate measurements. Every press of Complete set creates one completed set, even when several sets contain the same number of repetitions. The daily display therefore answers two different questions: how many sets did you complete, and how many repetitions did you record across them?
For example, suppose one set contains 10 reps and the next contains 12 reps. The daily record shows 2 completed sets and 22 recorded reps: 10 + 12 = 22. This is the expected result because the two completions remain distinct sets. If the totals appear inconsistent, first confirm that each set was completed once and then use Undo set to remove an accidental latest entry.
Each row in the Daily history list shows both the number of completed sets and the total repetitions recorded for that date. Reviewing those two values together is a more reliable accuracy check than looking at the repetition total alone.
Read the Rest Timer for Its Actual Job
The rest timer is a local convenience attached to a completed set. When a duration has been entered, completing the set can start that countdown. Skip rest clears it early, while a duration of zero leaves the counter usable without a countdown.
The countdown does not measure recovery quality, determine when your body is ready, or prescribe a recovery interval. It also does not detect movement, infer exercise form, estimate calories, or make a claim about a health outcome. Its only role is to display the interval you chose. Selecting a duration therefore records your decision; it does not turn the value into a recommendation.
Choose the Export That Matches Your Record
Review the Daily history list before exporting so you can confirm the dates, completed-set counts, and repetition totals you want to retain. Exports are optional. The browser holds the working history, while an exported file gives you a separate copy when that is useful.
| Export | What it contains | Practical use | Output boundary |
|---|---|---|---|
| CSV | One row per saved day with Date, Sets, and Reps columns | Reviewing structured records in a spreadsheet | The export represents the saved days in the local browser history |
| PNG | A 1080 by 1350 image with the Lizely mark, a total, and recent day rows | Creating a compact visual workout summary | The image excludes any URL or custom workout label |
Both exports happen in the browser through native canvas and Blob APIs. They do not turn the tool into a cloud database. If clearing browser data could remove a record you need, create the export first and keep the resulting file.
Account for Local Storage, Dates, and Devices
The rep value for each completed set is saved in browser local storage under counter:workout-rep-counter. There is no account, synchronization service, tracker, hidden upload, or API request for completed sets. Your log remains local to the browser where you entered it.
That privacy model comes with clear limits. Clearing browser data removes the saved history, and another device starts with an independent empty record. If local browser storage is unavailable, the page still displays the interaction currently open but reports that it cannot save a durable history. A visible total is therefore not proof that the record will survive a browser cleanup.
Daily dates follow the device’s local timezone. A session completed late remains attached to the local calendar date on which it was logged instead of being shifted by a UTC boundary. This makes the Daily history date check meaningful, provided the device’s local date is the date you expect.
Use a Final Accuracy Check
Run this brief check before leaving the counter or exporting the history:
- Confirm that Reps per set held a whole number from 1 through 1,000 and matched the set you intended to mark.
- Confirm that the optional rest duration fell between 0 and 3,600 seconds and reflected the interval you chose.
- Check that Complete set was pressed only after each set was finished.
- Compare today’s completed-set total with the number of sets you performed.
- Compare today’s repetition total with the reps entered for those sets.
- Use Undo set if the most recent completion was accidental, then recheck both totals.
- Review the dated Daily history rows and export a copy if you need the record outside the browser.
The central safeguard is the order of operations: configure the intended values, perform the set, press Complete set afterward, and verify what was saved. Because the tool records your entries rather than detecting your workout, that verification step is what turns a simple button press into a dependable workout log.
