OxyBio Oxy Respiratory Trainer | Breathe Easier with Stronger Lungs | Made with High Grade Silicone

Haven’t had for long. But it seems to do what it says. Exercises your breathing muscles. Makes me cough “stuff” out.

Muy buen producto

Does exactly what it is suppose to, help yo breath easily during a run.Onlest dislike, is the accumulation of saliva in ones mouth.

I'm sure it's a quality product but I didn't like the rubber mouth piece as it would make me nauseas. I put it right back in the box knowing I couldn't use it.

I use it while running on treadmill. Takes runs to new level. Made of high-quality materials. Easy to use and adjust. And clean as you will get saliva on it.

This breath trainer is easy to use and really does the trick. It definitely makes breathing hard while at it's hardest settings, but is easy at it's easy settings (as it should be). So twist the dial to where you feel comfortable and train away!

Unlike a typical Spirometer, this is a no fuss device that easily fits in a pocket. While I wouldn't use it public, it's a great lung exerciser that you could use in the car or in a private office. For an extra boost, you could use it while walking.There is one adjustment to control airflow, by allowing more or less through, depending on setting. Instructions included with a suggested routine. It really does give your lungs an exercise.The only negative - it tends to collect saliva, so you'll want to wipe or rinse it off before putting it back in your pocket!Overall this is a great lung exerciser that's easy to use.

This breathing trainer couldn't be easier to use - essentially, you just bite down and breathe! There's a simple barrel at the end to adjust resistance, and it works well. It's well made, but still seems a bit pricey for what it is. I can recommended this, but there might be more affordable options out there.
