Benefits include immediate calm right after use, which facilitates my morning meditation with more initial relaxation. As the Taoist's say: "Amateur meditators meditate to relax, professional meditators relax to meditate" - the O2 Trainer enables the relaxation effect for me right away. Second, the energy that I am experiencing throughout my day is significantly increased with use as well; definitely an increased skip in my step. I understand this is a contribution to my already athletic lifestyle and that I've been a serious athlete and healthy eater my whole life. (I'm 58 years old). My main sport for the last 35 years has been inline speed skating and for about 9 months of the year I'm skating about 50-60 miles per week. One thing I noticed since starting to train with the O2 Trainer is that I can breath more comfortably through my nose for the majority of my skate. This is significant as I've been working on this technique for years without any significant improvement. Today I skated in 45 degree weather in upstate NY and was mostly breathing out of my nose the whole time and felt like my stamina has found something I've been missing. Looking forward to increased benefit with continued use. Thanks Bas! Review: Skeptical guy proved wrong - The concept was so simple I was not expecting much. I was was 100% wrong. It is an amazing product it helps me with breathing but more than that it helps my core muscles stretch and strengthen. It actually helps my posture.

I have asthma so i'm looking for the one that will work best** A: Well I have the O2 trainer and I've researched some comparison videos if you have asthma probably both are gonna give you a little bit of trouble but I saw on one of the videos that the elevation training mask makes it difficult to breath out which according to bass rutten O2 trainer video isn't as conducive to your training one of the positives about the mask though however is that you don't have to wear the nose clamp thingy on the O2 trainer on the higher levels you WILL have to in order for it to work at it's optimum capacity. I hope this was helpful -Cheers **Q: Would this be comparable to just breathing thru your nose?** A: On the 1st 3-4 air hole sizes, yes, but then as you go smaller and smaller, it gets harder and harder. Level 12 is basically a giant pin hole. Also, because I can hear myself breathing, I find it easier to regulate my breathing and make sure my breaths are equal and smooth, which helps a lot too. **Q: What's the highest elevation it allows?** A: This product is not related to elevation. Listen to bas rutten himself talk about it, how and when he came up with it, and what it done for himself and many others. **Q: Why is there 2 different models? Is one older than the other? The more squared one looks like it has a better case and better made** A: Hello , We only carry the model as in the picture . This is available in Blue and green . The squared one was an older model and the new one with the round caps is the latest model . The mouthpiece is improved and the overall usage is better . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Measured Athletic and Energy Results - Beyond Expectation *by E***N on December 3, 2023* With just 3 weeks of consistent use (4-5 days per week) I have experienced significant and unexpected positive effects from this device.

I was was 100% wrong. It is an amazing product it helps me with breathing but more than that it helps my core muscles stretch and strengthen. It actually helps my posture. I'm a true believer ### ⭐⭐⭐⭐⭐ It Works Because It's Practical *by Y***E on June 12, 2014* After reading about this product, I wasn't sure if it would actually do anything, or if it would merely produce nothing more than a placebo type effect. After about a month of use during routine exercise, I noticed a marked difference in how quickly my breathing recovered when I didn't have the O2 Trainer. And I have only made my way to the fifth resistance cap. This O2 trainer is great because it is a practical size to actually bring along with you in a bag, it does not cover your face like an alien face hugger, cleaning is quick and easy, switching out the resistance caps is straightforward, and it all stores in a simple case. It is easy to bring along and grab before a workout or take along to work. There is nothing to break on it as it's made out of a rubber-type material. This is huge because I can just throw it in a bag and not worry that the bag gets sat on or crushed by something. I don't have to worry about scratching a faceplate or cross-threading a screw-on attachment. It comes in two simple colors, so there is no need to buy an outrageous neoprene sleeve to "hide" your device or anything. Wearing it is intuitive and doesn't require special training or practice. Also, for those who look at other O2 trainers as I did and notice that this device fails to cover the nose, realize that you can breathe out of your mouth, or use the nose clip that is included. All in all, this was a great purchase, affordable, durable, and is actually showing results that I can feel. To speak to the issue of saliva build-up in the device: Yes, it does tend to build up as your workout length or intensity does, but I will admit that I have been using it exclusively outdoors and it has not been an issue for that reason. It's not any more than you would get breathing into any device. Condensation will accumulate, but I believe it is manageable. Bottom Line: If you are looking for O2 resistance in a device that is practical and easy to integrate into whatever you want to do, the Bas Rutten O2 Trainer answers the mail. ## Frequently Bought Together - Bas Rutten O2Trainer: Breathing Muscle Training Device – Lung Power & Endurance Tool for Athletes, Singers & High-Altitude Performance – Diaphragmatic Respiratory Trainer – 16 Resistance Caps – Green - Bas Rutten O2 Trainer Natural Cleaning Lotion - All Purpose Cleaner - Created To Clean Respiratory Lung Training Device - 1 Count - Bas Rutten O2Trainer: Breathing Muscle Training Device – Lung Power & Endurance Tool for Athletes, Singers & High-Altitude Performance – Diaphragmatic Respiratory Trainer – 16 Resistance Caps – Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/1789748-bas-rutten-o2-inspiratory-muscle-trainer-green](https://www.desertcart.sk/products/1789748-bas-rutten-o2-inspiratory-muscle-trainer-green) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-28*
