efectivo en la montaña a mas de 4500 mtssnm

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!

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.

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.
