Breathing Trainer, Portable Respiratory Muscle Trainer with Adjustable Resistance, Compact Lung Exercise Device, Detachable for Easy Cleaning - Black

I'm at Respiratory Therapist. We teach our patients purse lipped breathing to create back pressure in their lungs when short of breath. This is NOT !!! a medical endorsement!!! This is a good training tool. I used it while riding a stationary bike. It helps recruit (in my opinion) more alveolar for greater capacity.

Works as attended.

Bought it for son he wanted it so bad but now he doesn’t ever use it but it does work

I love this in 1 week it trained me lungs and I can run for longer without breathing like am going to die.

1 week ago cant take a deep breath and when i ran i could only run super duper short distence and then i orded it and then i used it for one week and i could take a deep breath and i could run super duper far and get kind of tired and now i can sleep every night now

this product will help you improve your fitness, Ive been using it for months and it has helped my breathing alot.

As soon as we got this device, I had my husband start training his breathing with it. Sadly, it only kept making him throw up due to how large the mouthpiece is. He tried doing this a few times, but the only effect it had was making him throw up.

This item was just as advertised. You can change the settings on it so that it is just as hard to breathe in and out as you need it to be to exercise your lungs.
