Methodology

Core principles

• Clarity: every phase has a name, duration and cue.
• Control: pace, repetitions and guidance can be adjusted.
• Gradual practice: start gently and stop at any time.
• Safety boundary: wellness content is separate from diagnosis and treatment.

How an exercise is built

An exercise is a sequence of inhale, full-lung hold, exhale and post-exhale hold phases. Not every exercise uses all four. Duration can be measured in seconds or pulse beats.

How we assess content

• We check physiology and safety in health-institution and peer-reviewed sources.
• We distinguish findings in healthy people from evidence of treatment.
• We avoid absolute promises and state limitations.
• We connect intensive patterns with contraindications and stop signs.

Technical checks and updates

Automated and manual checks cover phase order, timing calculations, controls and cues. We update this methodology when stronger evidence appears or an error is found.
