Free US shipping
Secure checkout
Free replacement if damaged
Train your lungs the same way you train everything else — against resistance. This adjustable trainer makes your respiratory muscles work harder with every breath, so climbing stairs, finishing a run, or holding a set stops leaving you winded.
Adjustable resistance
Start easy and dial it up as you get stronger. Multiple levels mean the trainer grows with you instead of getting left in a drawer.
Built for daily use
Flexible, durable silicone that rinses clean in seconds — made to be used every day, not babied.
Fits in your pocket
Small enough to live in a gym bag, a car console, or a jacket pocket. No excuse to skip a session.
Minutes, not hours
A few focused minutes a day is the whole routine. It fits around your life instead of asking you to rearrange it.

Questions
Good to know
Most people use it for a few minutes a day, once or twice daily. Like any kind of training, consistency matters far more than long sessions.

Yes. The silicone mouthpiece rinses under warm water in a few seconds, and the whole trainer air-dries quickly.
