Respiratory Trainer | Lung Strengthening Breathing Exercise Device | Made in USA | Adjustable Bi-Directional Resistance | Medical Grade Silicone Mouthpiece | Carrying Case Included

I bought one for myself and my boyfriend. I am on a club swim team and my boyfriend trains for marathons. We love this product. I tend to use it in the mornings and evenings. I can take deeper breaths. It has helped with my swimming especially with my flip turns and staying underwater longer. My boyfriend said he can feel the difference as he runs also. We love this product.

I may or may not have undiagnosed sleep apnea. Everyone I've ever slept around tells me that I snore. I heard on a podcast that wind-instrument musicians have a dramatically lower incidence of sleep apnea, and the host mentioned he bought a breath resistance device to use in his workouts. I started doing breath resistance workouts with no equipment (more on that below) and noticed an improvement in my sleep quality within maybe 3 days or so. Specifically, I was sleeping through the entire night without waking up to go pee at 4am. I also started waking up after 7 hours of sleep mostly-fully rested (normally I need 8+). How do you do breath resistance workouts without equipment? Easy. Purse your lips and below. If you're not getting any resistance, purse your lips more. Problems with the no-equipment breath resistance training: 1) There's a limit to how much resistance I can put on my breath using just my lips. 2) It's harder to train inhaling for some reason. I had already dabbled with no-equipment breath resistance a year or two ago, but I fell off the habit because I just forgot. Honestly, I ordered this device to leave it on my bathroom counter, just so I could stare at something to remind me to do it. It turns out, I love this device! The mouth piece is super comfortable. I also like to think I'm well-tuned into what off-gassing plastic smells like, and this one doesn't seem to be a problem for off-gassing. Additionally, you're only using this device for 90 seconds, right? Because inhaling and exhaling are tuned using the same knob, I've learned that my inhaling is weaker than my exhaling. Oh well, the two will even out as I use the device longer. This one also looks more durable and more no-nonsense than the other name-brand product here on Amazon, the white bulb one. That one looks cheap honestly, this one is a durable piece of equipment.

they work great

Excelente producto

Great idea, it’s like a compact elevation mask. It just needs reworking in the lab. Mused and others have mentioned, spit falls a lot from these. Back to the lab guys

Works as good as advertised! Stick with it!! Recommend!!

TLDR: Decent quality material and construction. Mouth piece a little bit thin. Bi-directional resistance dial for customizable resistance both ways. No physical instructions. The mouth piece is a little thin but overall construction is decent with a resistance dial on the end. There is a card with a qr code for instructions but no instructions in the box. It should be washed before and after each use. Nice storage case. No information on durability yet.

It's good

I started using this respiratory trainer a few weeks ago to improve my lung strength and stamina, and it’s been surprisingly effective. The adjustable resistance makes it easy to start light and gradually increase intensity, which keeps training both challenging and motivating. Pros: • Compact and lightweight — easy to toss in a bag and use anywhere. • Adjustable resistance dial works smoothly, letting you tailor each session. • Feels durable, with no cheap or flimsy parts. • After consistent use, I’ve noticed deeper, fuller breaths and improved endurance during workouts. Cons: • The mouthpiece takes a little getting used to — feels awkward at first. • Doesn’t come with a detailed training guide, so you’ll need to pace yourself and figure out a routine. Overall: This little trainer really delivers on what it promises. It’s not a magic fix, but with regular use it absolutely strengthens your lungs and improves breathing control. Whether you’re an athlete, singer, or just someone wanting better respiratory health, it’s a solid investment.

Ótimo para fortalecer os pulmões!

It actually helps with breathing. But make sure u don't faint. Breathing thru this will put pressure on lungs. Use wisely read the pros and cons before using it. Keep it well maintained with warm water wash

Nice product with superb quality. Specially the mouth piece is soft and easy to use. I highly recommend this product.

Very useful
