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.

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.

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.
