Bas Rutten O2 Inspiratory Muscle Trainer - Green

I let Bas know how awesome it works for me on social media; just had to give this thing props on Amazon too. It's that good. I am a lifter that's had circulatory issues for as long as I can remember starting with a deviated symptom and other issues I won't mention. Sometimes I use it on the treadmill, between lifting sets, and during. This alone has improved my ability so sing+scream heavy metal and hardcore. I can now hold notes significantly longer and felt a difference in my lung capactiy and entire diaphragm. This thing rules. Thanks again, Bas!

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.

Incredible. The cardio advantage you gain is immeasurable. If Bas Rutten says it, it must be so

You will absolutely feel this thing working. I was using muscles in my abdomen I didn't even know I had. But at the end of the day this thing just doesn't feel that great in your mouth, and maybe it's just me, but mine would fill up with saliva during use and then start dripping out the breath holes during the exercises. If you are okay with that then feel confident buying and get ready to get your butt kicked!

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!

This is the best tool I reccomend I used this 10 minutes each day and my gas tank got better

Works as advertised. Genuinely helps with my breathing. Bas has a great product as expected from a champion.

Works great so far except the flappy piece on the side that is suppose to restrict airflow with the gasket broke . Is there anyway to order a replacement piece

Works just as advertised. Noticeable difference in how well I was able to breath in only a few days. It is built very sturdy as well. It looks like plastic but is actually made of some kind of silicone material. Shows a plastic nose clip; however the one I received was metal. Very happy with this product.

Super waste

Eu tenho o antigo o2 trainer e o novo. É um gadget bom para exercitar seus músculos respiratórios. A encomenda chegou bem e na data prevista.

I thought when I bought this it would be easy, I still am fairly low on the 02 trainer. This is not a miracle tool that will make you a great runner immediately, like everything it does take time to see improvement, but do not get me wrong the improvement is their and it is noticeable.
