Review: Sporco e difettoso - L'articolo è arrivato con quelli che sembravano pezzi di ganja sopra, dava l'idea di essere già stato aperto. Oltretutto la valvola che dovrebbe chiudersi durante l'inspirazione non sigilla bene e rende anche l'utilizzo di resistenze alte inutili. Lo terrò solamente perché è utilizzabile sigillando la valvola col dito, e perché non ho voglia di star dietro alla trafila per ottenere un rimborso. ## Features - Bas Rutten Respiratory Training Device: Designed by Bas Rutten himself, the O2 Trainer is a lightweight and portable breathing exercise device for lungs that helps increase inspiratory (inhalation) muscle endurance.

If you keep training with it the saliva build up will get less. Some people experience this, other experience a dry mouth (They will be good after a few weeks as well)But, we are coming out with a different mouthpiece since some people can't swallow with the o2trainer in their mouth, the new design will help with that. Also, we are coming out with new tests that will blow everybody away, really great things coming. For now I want you to do the same as what I do, take 30 deep breaths with the o2trainer on level 9 or 10. Sit dow, lean over, completely exhale (everything out) then explode with breathing in while you are sitting up (you can simply press the o2trainer against your mouth while doing this). Then go down again and exhale everything and repeat 29 times.This will take about 4 min. Do this for 6 weeks in the morning and evening, after 6 weeks one time a day will be fine. The result you get will be amazing, your core will get a huge workout as well, please try it out. I will come out soon with all the tests. Godspeed **Q: What is the maximum resistance setting in cm H20 for the blue and the green product?** A: Both colors are identical in how they work. It's 1mm, I (I am Bas) have been doing it for 5 years straight, everyday, I use setting 1.5mm. Doing setting 1 the correct way, it extremely hard. I used to do it in 2:15m (30 repetitions) but then realized I wasn't completely inhaling and exhaling, so when I made my technique perfect, it took me over 6 min. Do NOT focus on getting to the smallest size, focus on technique, its much more effective doing it correctly. I know you just asked for the size, but I just wanna mention this because pretty much many tell me they do setting 1, which when done correctly, I find very hard to believe. Godspeed! **Q: Does this fit children (ages 9-11?)** A: It's very young, I am sorry but you have task your doctor. I believe with supervision from a parent who makes sure they don't push too hard should be OK. But kids at that age are still developing, so please ask your Doctor. Tell him it's a device that controls the air intake, and that YOU can control the resistance, meaning, you would make sure they don't use lot of resistance. Thank you for your interest! **Q: so is it 4 sets of 30 reps,4 sets of 12,or 30 reps for 4 mins? some please explain.** A: There are videos on the official website for it. There are two different exercises now. A different routine too. Now it's pick the attachment and when you can do 30 reps under 3 minutes you move to the next smaller attachment and continue like that. No more sets and your really need to go watch the videos. ## Customer Reviews ### ⭐⭐⭐⭐⭐ As expected *by R***E on 10 October 2022* Product was delivered on time and as expected.

It really works. *by A***R on 3 June 2020* I am almost 40 and for my whole life I have felt like my cardio system was the weakest link in my body. I am fine with low rep heavy lifting but whenever it came to running or boxing I felt like I would always be out of breath within a few minutes. Doing more cardio helps of course but I could not help shake the feeling that there was something wrong with me, that for all the effort I put into the cardio I should be performing better than I was. I heard about this thing on Bas' Youtube channel and I did some reading around. I was skeptical. It seemed to me like you could just get the exact same effect breathing through a straw. But I love Bas' personality and have laughed many times at his crazy Youtube videos so I figured I would trust him and give this thing a try. So basically this thing restricts airflow when you are breathing in, and there is a valve that allows you to breathe out as quickly as you want. So you are only stressing the inspiratory muscles used for breathing in. And because your outward breath happens so quickly, effectively you are straining your inspiratory muscles 90% of the time that you are breathing. The load becomes almost continuous. It comes with a wide variety of hole sizes for people of all abilities. The widest hole (#1) is almost zero resistance and would be suitable for a senior with breathing difficulties. As a dude with above average fitness I started at #6. From the very first session I could feel some soreness in the muscles around my ribs, which I knew could only be a good thing. It means I was going to become stronger! Having one way resistance versus breathing through a straw was a big difference. I don't know how to describe it but from the first few breaths with this thing I could tell something was different to continuous airflow restriction. The more sessions I used it, the more I felt soreness in muscles that I never knew I had. Muscles that clearly had never been trained before my whole life. I progressed quickly and I decreased the hole diameter by about 1 with each session. Now I am on hole #11, which is very significant resistance and I think I am going to stay here for a while. Hole #12 would be for literal professional athletes. Now when I am running or boxing I just don't feel out of breath. My heart rate still hits 170 like before but I am not gasping for air. It is really weird it almost feels like a super power! I can literally feel several mm thick of muscle around my ribs that I never had before my whole life. It feels awesome. I can expand my ribcage now to a size I never thought possible for my skeleton. It looks like the massive chest poses Arnold did in bodybuilding. This whole thing is mindblowing to me. I have been hitting the weights and bikes for more than 20 years and still nothing ever properly trained my breathing muscles all this time?! Why aren't more people talking about this?! The only downside is that I feel like it is expensive for what it is - basically some molded pieces of rubber. Also it smells/tastes weird and.. well... rubbery. But it works, and it works even better than I expected, and Bas is awesome so 5 stars. One reviewer was complaining that this thing caused him to lose his voice. I don't know what's up with that guy, but that sure as hell hasn't been a problem with me. ## 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 – Blue - 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 – Green --- ## 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.hr/products/496591396-bas-rutten-official-o2-respirator-breathing-lung-trainer](https://www.desertcart.hr/products/496591396-bas-rutten-official-o2-respirator-breathing-lung-trainer) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-20*
