Assessment

Power Capacity

Measure your response to three power-breathing rounds and brief holds. Your result sets a controlled activation pace.

Breathe through your noseDo not force holds

Protocol

  1. 1. Complete 30 metered power breaths, then end the hold at first clear air hunger.
  2. 2. After each empty hold, take the guided recovery inhale, hold full, then exhale into the next round.
  3. 3. Your average hold unlocks one of five priming paces for future tests and the matching program.

Never force a hold. Every round ends the instant air hunger is clear.

The Power Capacity Test

A free, guided breath retention baseline. Three rounds of 30 metered power breaths, holds that end at first clear air hunger, and a level from Sparkmaker to Firekeeper that unlocks the priming pace matched to you.

Why this matters

Retention time only means something under a fixed protocol.

Wim Hof-style rounds make holds longer by design — fast breathing lowers CO₂ and delays air hunger. Comparing holds across different apps, videos, or moods is noise. Auralize standardizes the dose so your retention numbers become an actual training signal.

Metered, not chaotic

The 30 breaths per round are paced for you at your current level, so every retest uses the same dose and your numbers stay comparable.

First-urge holds only

Every retention ends at the first clear air hunger — never at maximum strain. That rule is both the safety design and what makes the score repeatable.

A profile, not one number

You get four signals — starting hold, third-round hold, ramp response, and average — plus a level from Sparkmaker to Firekeeper that sets your priming pace.

Five levels

Where your average hold lands.

Auralize maps your average retention across the three rounds to product levels, each unlocking a faster metered priming pace. These are training heuristics for this exact protocol — not clinical categories, and not comparable with holds from other methods.

Level 1

Sparkmaker

Under 30s avg

Early retention range. The starting pace keeps rounds controlled while capacity builds.

Level 2

Igniter

30–60s avg

A developing base with room to lift both the cold-start and round-three access.

Level 3

Firebringer

60–90s avg

Solid enough to treat power breathing as repeatable capacity training.

Level 4

Firewalker

90–120s avg

Strong average holds — the next gains come from start and ramp together.

Level 5

Firekeeper

Over 120s avg

Elite for this standardized three-round protocol, with the fastest priming pace unlocked.

The protocol

How the power capacity test actually works.

Roughly 8–10 minutes, fully guided, with the pacing metered for you. Every hold ends at the first clear urge — that is a rule, not a suggestion.

Each of the three rounds starts with 30 metered power breaths — full, active inhales with relaxed exhales, paced by the orb at your current level. At the end of the round you exhale and hold empty, ending the hold the moment air hunger is clear. A guided recovery inhale and short full hold close the round before the next one begins.

The rounds temporarily lower blood CO₂, which is why later holds usually run longer — and why the test reports a profile instead of a single number: your cold-start hold, your third-round hold, the ramp between them, and the average that sets your level. See the power breathing guide for the mechanism and its limits.

Your average unlocks one of five priming paces and calibrates the 21-day Performance Priming Protocol — controlled activation work that uses your measured capacity, not a generic template. When the program completes, a retest is queued so the next prescription uses fresh numbers.

Frequently asked

Common questions about power breathing capacity.

What is the power capacity test?

A guided baseline for power breathing: three rounds of 30 metered breaths, each followed by an empty-lung retention hold that ends at your first clear air hunger, then a guided recovery inhale and full hold. Auralize scores your starting hold, third-round hold, ramp between them, and average retention.

Is this the Wim Hof Method?

It measures your response to the same rounds-plus-retention structure that the Wim Hof Method popularized — Auralize implements it as Power Breathing. The test itself is not affiliated with WHM; it is a standardized in-app protocol so your numbers are comparable with your own history.

What is a good breath retention time after power breathing?

Auralize maps your average hold across the three rounds to five levels: under 30 seconds is Building, 30–60 is Developing, 60–90 is Solid, 90–120 is Strong, and above 120 is Elite. These are product training bands for this exact protocol, not clinical categories, and they are not comparable with holds from other protocols.

Why do my holds get longer in later rounds?

The fast breathing rounds temporarily lower blood CO₂, which delays the air-hunger signal that normally ends a hold. That is why Auralize reports a ramp number — the difference between your first and third hold — as a signal of how strongly you respond to the protocol, and why retention time is not a measure of oxygen capacity.

What do start, third, and ramp mean on my result?

Start is your first-round hold — your cold-start access with no protocol assistance. Third is your third-round hold after the rounds have accumulated. Ramp is third minus start. Together with the average they describe your current profile: some people start strong but ramp little, others unlock most of their capacity only after the rounds build up.

What does my result unlock?

Your average hold unlocks one of five priming paces — Sparkmaker, Igniter, Firebringer, Firewalker, or Firekeeper — which sets the metered breathing speed for future power sessions, and calibrates the 21-day Performance Priming Protocol if you choose to start it.

Is power breathing safe?

The protocol deliberately ends every hold at the first clear air hunger — you never force or extend a hold. Even so, fast breathing can cause tingling or lightheadedness, so take the test seated in a safe place, never in or near water, and never while driving. Skip it entirely if you are pregnant, prone to fainting or panic, or managing cardiovascular, respiratory, or neurological conditions without clearance from your clinician.

What does the test cost? Do I need an account?

The test is free and runs in your browser with full guidance and metered pacing. No signup is required to take it and see your result. Saving your level, unlocking your priming pace across the app, and starting the Performance Priming Protocol requires a free Early Access account.
