What athletes are saying after consistent training with the Iron Breath Mask.
★★★★★
Honestly bought this as a last resort. My cardio in sparring was a joke....gassing out in round 2 every time. Didn't fully believe it would work but figured whatever. 3 weeks later my training partner asked if I'd been doing extra conditioning. I hadn't. Just this
★★★★★
I've blown up at mile 22 in every marathon I've run. Tried everything better nutrition, more long runs, nothing fixed it. Used this 3x a week for 8 weeks before my last race. Made it to mile 25 before my breathing started to crack. PR by 6 minutes. I'm not saying it's the only reason but it's the main thing I changed.
★★★★★
First session I lasted 11 minutes before I had to take it off. Felt embarrassing. Stuck with it. By week 3 I was wearing it through full metcons. My Fran time dropped by 40 seconds and I didn't die at the end. Small thing but it adds up.
★★★★★
I was ready to return it after the first week. Felt uncomfortable and I wasn't sure I was using it right. Kept going anyway. Somewhere around week 3 I noticed I wasn't dreading the later rounds as much. Not a miracle but it does what it says.
★★★★★
The size fits well, no issues there. Takes maybe a week to get used to breathing with it. first few sessions are weird. But after that it becomes normal and you start to notice on days you train without it. Your breathing just feels more controlled. Hard to explain until you feel it yourself
★★★★★
Been cycling seriously for 6 years. Always felt like my legs had more in them than my lungs would allow on climbs. Used this through winter training. Spring came and my threshold efforts felt genuinely different. I could push deeper before the breathing became the limiter. My FTP went up 12 watts. Can't prove causation but the timing lines up.

Who It's For
Your Sport. Your Edge.
Whether you fight, run or train, your breathing is either working for you or against you.
Fights Are Won By The One Who Still Has Gas.
You can have better technique, better training, better everything. But if you're sucking wind in round 3 and your opponent isn't, none of that matters. Train your breathing like you train your hands.
- Replicate the breathing pressure of being controlled or smothered
- Stay sharp in the late rounds when opponents start fading
- Stop gassing out before the fight is over
★★★★★
My cardio in sparring has completely changed. I'm not the one gassing anymore.

Build An Engine That Doesn't Quit.
You know the moment. The WOD gets heavy, your lungs are on fire and your pace cracks before your muscles give out. Train your breathing under stress and that moment starts happening later and later.
- Push deeper into AMRAPs without the wheels falling off
- Recover faster between rounds so you can go again
- Be the one still moving when everyone else is bent over
★★★★★
Used it through a full Murph prep. My breathing held up where it used to fall apart.

Race Day Should Feel Easier Than Training.
When your breathing breaks down your pace breaks down with it. Train your respiratory muscles during your hard sessions and race day starts feeling like you have something left in the tank when everyone around you is fading.
- Hold your pace deeper into races without blowing up
- Stop letting your breathing be the reason you slow down
- Use it on interval days and tempo runs for maximum benefit
★★★★★
PR'd my half marathon by 4 minutes. I added this to my interval sessions 8 weeks out and it made a real difference.
