Breathing Baseline: Resting Breath Rate and Breath-Hold Capacity
30 minutes (two breath rate measurements + BOLT test, all in one session)
Breathing quality is measurable through two accessible metrics that require no equipment beyond a timer: resting breath rate and breath-hold time (the BOLT score — Body Oxygen Level Test). Resting breath rate reflects respiratory efficiency — the lower and slower the resting breathing pattern, the more efficient the breathing. The typical resting breath rate for adults is 12–20 breaths per minute; trained individuals with functional breathing patterns may be closer to 8–12 per minute. The BOLT score measures breathing-specific cardiovascular fitness by timing the comfort zone between natural exhalation and the first involuntary urge to breathe — it does not measure maximum breath-hold willpower. Establish both metrics in the same session. Resting breath rate: lie or sit quietly for 3 minutes, then count the number of complete breaths (one inhalation + one exhalation = one breath) over exactly 2 minutes using a timer, and divide by 2 to get breaths per minute. Take 2 measurements 10 minutes apart and average them. BOLT score: breathe in and out naturally, hold the breath after a gentle exhale (mouth closed), and time until the first involuntary movement or urge to breathe — this is not a maximum hold contest; stop when you first feel a clear urge, not when you cannot continue. The BOLT score reference: below 10 seconds = very low; 10–20 = poor; 20–30 = moderate; above 30 = good breathing efficiency.
Proof required
Submit your M1 breathing baseline: (1) resting breath rate — two measurements taken 10 minutes apart and their average (breaths per minute); (2) BOLT score — timed from natural exhale to first involuntary urge to breathe, in seconds. Note the conditions: whether you were sitting or lying, time of day, and whether you had been active within the previous hour.
What gets checked
- Resting breath rate is the average of two measurements, not a single count — breathing rate varies within a session; two measurements 10 minutes apart reduce the variability
- The BOLT score is timed to the first involuntary urge to breathe, not to the limit of willpower — willpower-based breath holds are not repeatable or meaningful as a breathing efficiency measure; the BOLT specifically measures the first comfortable urge point
- Neither measurement is taken within an hour of exercise — acute exercise significantly reduces resting breath rate reliability and inflates the BOLT score; both must be taken in a rested state

What a verifier looks for
- Both metrics must be present in M1. Resting breath rate alone or BOLT score alone is an incomplete breathing baseline — ask for both
- The resting breath rate should be the average of two measurements, not a single reading. If only one count is given, ask whether the person measured twice
- The BOLT score notes should confirm it was taken to the first involuntary urge, not to maximum hold. If the person records a very high BOLT score (above 40 seconds) without prior training, ask whether they held to the urge or to their limit
- Watching or counting breaths during the resting breath rate measurement — self-observation causes involuntary changes in breathing rate; set a timer and count unobtrusively or have someone else count
- Pushing the BOLT score to the maximum breath-hold duration — this converts the BOLT into a willpower test, which is not what the metric measures and which is not repeatable; the first involuntary urge is the correct stopping point
- Measuring resting breath rate immediately after getting up or after any mild physical activity — even light movement elevates the respiratory rate; the measurement requires sitting or lying quietly for at least 3 minutes beforehand
Eight Weeks of Breathing Practice
8 weeks (5–10 min daily practice, weekly BOLT retests at Weeks 2/4/6/8)
The 8-week programme develops more functional breathing patterns through two complementary practices: diaphragmatic breathing (using the full capacity of the diaphragm rather than shallow chest breathing) and reduced-volume breathing (gradually learning to breathe less air per minute at rest, which is the key mechanism behind BOLT score improvement). Both practices are nasal — mouth breathing at rest actively works against breathing efficiency by bypassing nasal airflow conditioning. Diaphragmatic breathing practice: 5 minutes daily lying on the back, one hand on the chest and one on the abdomen, focusing on the abdomen rising first and more than the chest. Log whether you completed the practice each day. Reduced-volume breathing (also called relaxed nasal breathing): spend 5–10 minutes daily deliberately breathing less than your urge to breathe — a gentle air-hunger sensation is correct; breathlessness is not. Log daily. Optional: extend to 15–20 minutes of any sustained moderate-intensity nasal-only activity (walking, cycling) per session, working up gradually. Log weekly: diaphragmatic practice days, reduced-volume practice days, and nasal-only activity minutes.
Proof required
Submit (1) daily practice log for all 8 weeks showing diaphragmatic breathing practice (yes/no per day) and reduced-volume practice (yes/no per day); (2) weekly BOLT score retests at Weeks 2, 4, 6, and 8, measured using the same protocol as M1; (3) a brief note at each 4-week point on what changed in how breathing feels day-to-day.
What gets checked
- Both diaphragmatic and reduced-volume practices are logged daily — the two practices address different aspects of breathing function; skipping one produces partial improvement only
- Weekly BOLT score retests at Weeks 2/4/6/8 use the same protocol as M1 — same rested state, same first-urge stopping point; a change in protocol makes the trend meaningless
- The daily log covers all 8 weeks including days when practice was missed — a complete log that shows some missed days is far more credible than a perfect-looking log, and improvement happens even without 100% adherence

What a verifier looks for
- The daily log should show both practices logged separately. If only one practice is logged throughout, ask whether the other was done informally or not at all
- The BOLT score retests at Weeks 2/4/6/8 should all use the same rested-state first-urge protocol as M1. If scores fluctuate dramatically week to week (more than 10 seconds), ask about the testing conditions — it may indicate inconsistent protocol
- The qualitative notes at Weeks 4 and 8 should describe something specific about how breathing feels — 'less breathless on stairs' or 'falling asleep faster' are meaningful observations; 'it's better' is not specific enough
- Doing only the diaphragmatic practice and skipping the reduced-volume practice — the BOLT score specifically measures breathing volume efficiency; diaphragmatic breathing improves the pattern but reduced-volume practice is the key driver of BOLT improvement
- Forcing the breathing pattern consciously all day rather than practising in dedicated daily sessions — constant forced breathing awareness is unsustainable and often counterproductive; the 5–10 minute daily practice period is the intervention; general breathing awareness develops naturally over weeks without forcing it
- Retesting the BOLT score after exercise or when tired — the BOLT is only valid when measured in a rested state; post-exercise BOLT scores are not comparable to the rested M1 baseline
Final Breathing Measurements and Comparison
30 minutes for M3 measurements at Week 8
At Week 8, remeasure both metrics using exactly the same protocol as M1. Resting breath rate: two measurements 10 minutes apart in a rested state (not within an hour of exercise), averaged. BOLT score: natural exhale, breath-hold to first involuntary urge, timed in seconds. Provide a side-by-side comparison table showing M1 and M3 for both metrics. Provide an attestation from one named person who was present during the 8-week period and observed the daily practice — a household member, partner, or exercise companion who can describe what they noticed about the breathing practice.
Proof required
Submit (1) M3 resting breath rate (two measurements and their average) and M3 BOLT score (same protocol as M1); (2) a side-by-side comparison table of M1 and M3 for both metrics; (3) an attestation from a named person who observed the 8-week breathing practice.
What gets checked
- Both M3 metrics use exactly the same protocol as M1 — same rested state, same two-measurement average for breath rate, same first-urge BOLT protocol
- The comparison table shows both metrics at M1 and M3 — a comparison of only the BOLT score without the breath rate (or vice versa) is an incomplete outcome
- The attestation describes observed practice behaviour, not just the final results — 'they did the breathing exercises every evening before bed for the last 2 months' is observation; 'they said their breathing improved' is not

What a verifier looks for
- Both M3 metrics must be present. If only the BOLT score is submitted at M3 without the resting breath rate, ask for the breath rate measurement
- The M3 BOLT score should be taken under rested conditions. If the person notes they were anxious or recently active when retesting, the score may not be comparable to M1
- The attestation should describe observed practice behaviour across the 8 weeks, not just the final state. Ask whether the attesting person was present throughout the programme or only at the end
- Measuring M3 BOLT score after a particularly good night's sleep or at a time when the person feels unusually calm — exceptionally calm states can inflate the BOLT by 5–10 seconds; the M3 should be measured under the same typical-day conditions as M1
- Providing only a single resting breath rate measurement at M3 rather than the two-measurement average — the M1 baseline used two measurements; M3 must use the same method for the comparison to be valid
- Reporting the M3 BOLT as a willpower breath-hold rather than the first-urge point — after 8 weeks of training, it becomes tempting to hold longer to demonstrate improvement; the BOLT must still be stopped at the first involuntary urge
