Review: Measured Athletic and Energy Results - Beyond Expectation - With just 3 weeks of consistent use (4-5 days per week) I have experienced significant and unexpected positive effects from this device. 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'm a true believer

## Questions & Answers

**Q: So using this thing at a gym on the treadmill isn't very practical due to the saliva buildup?**
A: Steven, this is Bas, how are you doing? 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.

### ⭐⭐⭐⭐⭐ Measured Athletic and Energy Results - Beyond Expectation
*by E***N on December 3, 2023*

### ⭐⭐⭐⭐⭐ Skeptical guy proved wrong
*by G***1 on June 26, 2026*

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'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.
