How many stations should a circuit have?

Four to eight is a workable range for most sessions — enough variety to cover different areas of the body without the sheet becoming unwieldy to read mid-workout. More stations than that usually means the individual work periods need shortening to keep the whole circuit a sensible length.

Why isn't there a rest after the last lap?

Because a session ending on a rest wastes that time — there's nothing left to recover for. The lap rest is only added between laps, which is why the total time is exactly the sum of the blocks shown rather than an estimate padded with a trailing rest nobody needs.

Workout Circuit Generator

Turns a list of stations — your own, or the four it starts with — into one full circuit with a round count, the rests between stations and laps, and a running total time. It does not choose the exercises: the site's core, upper-body, lower-body and cardio pickers each suggest one, and this is where they become a session.

Stations

One per line. Each lap works through all of them in order.

4 entries

Rounds

How many times round the whole circuit.

Work (seconds)

How long each work period lasts.

Rest (seconds)

Between work periods. Zero means continuous work.

Rest between laps (seconds)

The longer break after a full circuit.

Warm-up (seconds)

Optional. Zero leaves it out entirely.

Cool-down (seconds)

Optional. Zero leaves it out entirely.

Seed (optional)

A word that brings the same session order back.

Shuffle the order of the list

What this generator does

Produces a full circuit rather than a single movement, which is the difference from every other fitness generator here — those give you one exercise to slot in, this gives you the session.

How to use this tool

List the stations, one per line, or keep the four provided.
Press Build session for the circuit.
Complete the rounds shown, or change a figure and build again.

Understanding the controls

Stations: One per line. Every lap works through all of them in the order shown, which is what makes it a circuit rather than a set of intervals.
Work and rest: The work at each station, and the short rest before moving to the next. Together these set the pace of a lap.
Rest between laps: The longer break after a full circuit. Leaving it equal to the station rest turns the whole session into one continuous run of stations.
Rounds: How many times round. With the station count this fixes the total work, shown above the table as you change it.

Worked examples

4 stations, 3 laps, 45s work and 15s rest: 12 work blocks, 9 short rests and 2 lap rests — about 13 minutes with a minute between laps.
One lap: No lap rest at all, because there is no second lap to rest before.
Equal rests: Setting the lap rest to match the station rest makes the whole circuit one continuous sequence.

Common use cases

Home or gym circuit training
PE lesson activity planning
Breaking a single-exercise routine

How this generator works

A lap is every station worked once in order, with the short rest between them but not after the last one. The longer lap rest is added between laps and deliberately not after the final one, because a session ending on a rest wastes the last block. The total is summed from the blocks shown, so it always matches the sheet rather than being an estimate.

Randomness and fairness

Nothing is random unless you shuffle the station order, which changes the running order without changing the work. Every station still appears exactly once per lap however the shuffle lands. A seed makes that shuffle reproducible, which matters when the same circuit is run by two groups in different halls. It is deterministic, not cryptographic: the running order follows from the word.

For how randomness is produced across the whole site, see how Generate Random works.

Limitations and good to know

Every station is given the same work time, so a circuit mixing a heavy compound lift with a light mobility drill will overrun one and underrun the other.
Equipment and space are not modelled. A circuit needs its stations set up in advance, and the sheet cannot tell you that two of them need the same kit.
A circuit is usually run by a coach calling the changes, and the countdown here counts the station lengths rather than the reps inside them. If your stations are for reps and not for time, the clock has nothing to count.
With a group, the station count usually needs to match or exceed the number of people or pairs, which is a constraint the tool does not check.

Practical tips

Read the whole circuit before starting so you can set up the equipment once rather than between every station.
Scale the reps to what you can complete with good form on the last round, not the first.

Privacy and your data

The stations you type stay in your browser and are never uploaded or stored — closing the tab discards them. What is measured is that a circuit was generated and how many blocks it has, never the station list itself.

Not personalised advice — check with a medical professional before starting a new exercise routine, especially with an existing health condition.
