THE PROBLEM
Your lungs lose 1% of their capacity every year after 25.
You train your legs. You train your core. You track your heart rate. But the muscle that powers every rep, every mile, and every recovery breath? Nobody trains it.
Weak breathing muscles cap your VO2 max, spike your anxiety, cost you sleep, and drop your stamina — quietly, daily, for decades.
Prolungs exists to flip that.

QUESTIONS
Everything worth asking.
How does a breath trainer actually work?
A resistance breath trainer makes your inhalations and exhalations slightly harder against a calibrated valve. Your diaphragm and intercostal muscles adapt the same way any muscle does under load — they get stronger. Five to ten minutes a day for several weeks measurably improves how much air you can move and how efficiently you use it.
Can breathing exercises really improve athletic performance?
Yes. Peer-reviewed studies show inspiratory muscle training improves endurance performance by 3–5%. For a marathon runner that can mean shaving 9–15 minutes off a finish time. For a lifter it means recovering faster between sets. Stronger breathing muscles stop stealing oxygen from the muscles doing the work.
Is inspiratory muscle training safe for people with asthma or COPD?
Resistance breath training is widely used in pulmonary rehabilitation, but it isn't a medical device and isn't intended to treat any condition. If you have a diagnosed respiratory condition, talk to your doctor before starting and begin at the lowest resistance setting.
How long before I see results?
Most people feel a difference within two weeks — easier deep breaths, less breathlessness on stairs, calmer recovery between intervals. Measurable lung-capacity improvements typically show up between week 4 and week 8 with daily 5–10 minute sessions.
What's the difference between the Breath Trainer and the Spirometer?
The Breath Trainer (uPro) builds your respiratory muscles with calibrated resistance. The Digital Spirometer measures your lung capacity and breath quality so you can track progress. Trainer = the workout. Spirometer = the scoreboard. Most people start with the Trainer; serious trackers add the Spirometer.
Do I need the app to use the physical devices?
No. Both the Breath Trainer and Spirometer work fully on their own. The app adds guided protocols, BPM-controlled breathwork sessions, and progress tracking — useful, but optional.
How does Prolungs compare to Airofit or POWERbreathe?
Airofit and POWERbreathe focus on a single device. Prolungs is the only ecosystem that combines a guided app, a physical resistance trainer, and a digital spirometer designed to talk to each other. You get the workout, the protocol, and the measurement in one system.
Is there a money-back guarantee?
Yes. Every physical product comes with a 30-day money-back guarantee. If you don't feel a difference, return it within 30 days of delivery for a full refund — even if it's been used.
What's your shipping policy?
Orders placed before 2pm local time on business days dispatch within 24 hours. Standard shipping is free on orders over $50; express options are shown at checkout. Every shipment includes end-to-end tracking.
Is the app available on iOS and Android?
The Prolungs app runs in any modern browser at app.prolungs.com — iOS, Android, desktop. Native apps are on the roadmap. Save the web app to your home screen and it behaves like a native app.
