Respira Breath Trainer

Respira turns breath-hold training into something you can actually follow. Nine guided exercises take you from your first calm four-count breath all the way to full O2 tables — each one with a moving visual, a voice that tells you what to do next, and a timer that never makes you count in your head.

Take the Max Breath-Hold Test once, and your CO2 and O2 tables generate themselves from your real personal best. No copying numbers off a forum. No tables that are too easy to matter or hard enough to hurt.

NINE GUIDED EXERCISES

Beginner • Box Breathing — equal inhale, hold, exhale, hold. The mental reset button. • Rectangle Breathing — longer holds than breaths. A gentle step toward apnea. • 4-7-8 Breathing — deep relaxation and a real lung stretch. • Guided Relaxation — the pre-hold wind-down that drops your heart rate. • Lung & Diaphragm Stretch — flexibility for the muscles that actually breathe.

Intermediate • CO2 Table — same hold, shrinking rest. Teaches your brain that CO2 is not the enemy. • Apnea Walk — hold while walking, with a step counter you tap as you go.

Advanced • O2 Table — rest stays fixed, holds grow. Adaptation to genuinely low oxygen.

The Test • Max Breath-Hold Test — one guided maximum attempt. Sets the personal best every table is built from.

BUILT TO BE FOLLOWED, NOT WATCHED

A breathing circle expands and contracts in real time; box exercises trace a dot around a square so you always know which side you are on. Voice cues call every phase change out loud, tones chime, and haptics tap your wrist — turn on any combination, or all three, or none. The screen stays awake for the whole session, and audio keeps playing when you lock your phone and close your eyes.

TWO STRUCTURED PROGRAMS

• Foundations — 2 weeks, 5-10 minutes a day. Opens and closes with a Max Test so you can see exactly what you gained. Zero blackout risk throughout. • Road to 3:00 — 4 weeks of CO2 then O2 progression for anyone already holding about a minute.

Programs advance by session, not by calendar date, so a missed day never resets your plan or punishes you.

PROGRESS THAT MEANS SOMETHING

Personal bests per exercise, a full session history with how each one felt, a heat calendar of your training days, hold-time trend charts, current and longest streaks, and 26 achievements — from your first finished session to holding past the first contraction for a full minute.

SAFETY IS PART OF THE APP

Every exercise carries its own safety notes, and the serious ones say plainly what they require: lie down, never in water, one table per day. Respira will not let you stumble into an O2 table on day one — it asks for a Max Test first.

NEVER practice breath-holding in or near water. Shallow-water blackout kills strong, experienced swimmers, and it gives no warning. Do tables and max attempts lying down or seated on something soft, never standing, never while driving. Stop at dizziness or tingling. If you are pregnant, or have a heart, lung, or blood-pressure condition, talk to a doctor first. Respira is a training tool for healthy adults, not a medical device, and nothing in it is medical advice.
