The muscles you forgot to train

Why train your breathing?

You train your legs, your core, your arms — but the muscles that power every breath get no attention at all. Iron Lungs™ changes that with a few minutes of resistance breathing a day.

Stronger breathing muscles

Adjustable resistance on every inhale and exhale makes your respiratory muscles work harder, session after session.

Better breath control

Slow, deliberate breathing through the trainer builds control you can feel when the pace picks up.

Hard sessions feel easier

Over time, intense exercise feels more manageable when your breathing isn't the first thing to give out.

Minutes a day

No hour-long routines. A few focused minutes daily is all it takes to start building stronger breathing.

Resistance training

How a session works

01

Set your resistance

Turn the dial to a level that feels challenging but comfortable.

02

Breathe slowly

Inhale and exhale through the trainer in slow, controlled breaths.

03

Level up over time

As your breathing muscles get stronger, increase the resistance.

Like a dumbbell for your lungs

Resistance your breath can feel.

Iron Lungs™ works on a simple principle: make the air harder to move, and the muscles moving it get stronger. The adjustable dial resists both directions of your breath, so every session trains the full breathing cycle.

Start light, breathe slow, and turn the dial up as you get stronger — progressive overload, applied to your breathing.
