Train your breath.Own the rest.
Build the muscles that power every breath.
5 minutes a day.
One muscle POWERS it all.
Most people never train it.
Your diaphragm — your primary breathing muscle — fatigues under hard effort. The respiratory muscle metaboreflex redirects blood flow from working muscles to support breathing. Performance falls off.
OXYCURL builds your breathing muscles with two-way resistance that forces real adaptation.

How it works
Your diaphragm fatigues
When breathing muscles tire, your body triggers the metaboreflex — redirecting blood away from working limbs to keep you breathing. Performance collapses.
Resistance builds strength
OXYCURL adds calibrated load to each inhale. Like weight training for your diaphragm — progressive overload that forces adaptation in 4–12 weeks.
Your threshold moves up
Stronger respiratory muscles delay the metaboreflex. More oxygen stays where you need it. Longer hold. Stronger paddle. Faster recovery.
Breathe into your belly, not your chest. Find the motion.

What they say
“Mostly use it on easy treadmill days. Five minutes with resistance and I can definitely feel my breathing working."
"Not random drills, just one setup that actually makes sense for all the ways I do. Part of my morning routine now, and most days I just toss it in my bag, case and all. Simple and legit."
“The paddle out used to cook me way too early. My breathing feels much steadier now, especially through longer sessions. I’ve also started doing a little breathwork before getting in.”
"Started using this thing daily a couple weeks before season. First big tour out, I was skinning uphill through deep snow faster than the guys while they were coughing their lungs out behind me lol. And I’m the shortest one in the crew."
“Honestly bought it for the trainer, but the case is way more useful than I expected. Clips straight onto my pack.
Breathwork at the top hits different ;)"
“I do a few rounds before longer rides to warm up my breathing. Makes a huge difference.”

Everything is designed to help you start simple, progress gradually, and train wherever you are.
OXYCURL Trainer is a respiratory muscle trainer (RMT) designed to strengthen the muscles you use to breathe. Think of it like a dumbbell for your breathing system. With consistent use, stronger breathing muscles can help improve endurance, control, and recovery over time — starting with just a few minutes a day.
Place the mouthpiece in your mouth, set your resistance level, and breathe fully through the device. OXYCURL adds adjustable resistance to both inhale and exhale, making your diaphragm and respiratory muscles work harder — and stronger over time.
Start with 5 minutes a day at a comfortable resistance level. First, focus on feeling your diaphragm and finding the right breathing pattern. As your breathing muscles adapt, gradually increase the load. Once the basics feel natural, move into our guided breathing protocols.
Many users feel a more open, activated breathing feeling after the first session. Most begin to notice a real difference within the first week, while measurable strength gains usually build over the first 4 weeks. The full training cycle is designed to progress over 12 weeks of consistent use.
