Bas Rutten O2 Inspiratory Muscle Trainer - Blue

This is a piece of equipment everyone should have yet don't realize they need. This is probably my fifth or sixth I have purchased for myself and family members. It is gaming change in training how you breath. Well built device. A must buy.

Really helps athletic performance

Great product

I stumbled upon this product through an advertisement on sherdog.com and decided to buy it through amazon. I am 46 and in very good shape. I do lots of high intensity interval training - primarily 12 to 16 minute tabatas. I thought the logic behind this product made sense to improve my breathing during my workouts which usually leave me out of breath when complete. I began last Wednesday by doing the recommended breathing exercises and then did my first workout using the #1 filter. I had no problem with it and my next workout the next day I used the #2. I used #3 on my Saturday and Sunday workouts and used the #5 today (Monday). I definitely feel it getting tougher now to breath in but have not slowed much in my workouts or am I gasping for air doing my intervals. I may up the filter to #6 on my next workout but I think this week is more of an experimental period and think I will likely be increasing the filters at a much slower rate in upcoming weeks. If you just started exercising I wouldn't recommend using this device until you can consistently get through your workouts and workout often. I think it is excellent for for anyone trying to improve their breathing and fitness levels. One thing I have noticed is that as soon as my workout is over and I remove the o2trainer from my mouth and the nose clip - I notice I am not panting like I usually do. When I am not doing anything strenuous during the day my breathing feels very relaxed and effortless. It is a good feeling. The saliva problem that many reviewers mentioned is no big deal for me. I work out in my own garage gym and sometimes on rest intervals I pop it out and wipe it off really quick and pop it back in my mouth. I used it for burpees, sprints on the air-dyne bike, jumping rope/double-unders, thrusters etc and have no problems with it and other than making my breathing sound louder it is a comfortable device and I plan to keep using it. It makes you more aware of how you are breathing which I think is a good thing during a workout. I will follow up this review in a few weeks. So far I am impressed. I want to see how this translates into how I feel when I am running trails. If I feel like I can run forever then I will give this product one extra star.

I use this regularly for breathing and cardio training. It works better than expected to ensure my lungs, and oxygenation are working 100%

Used it till I didn't anymore.

I’ve had this for a decade I think. Just now getting through my reviews. This is an absolute workout! I love Bas! I also have the BAS trainer fighting pad thing. Which I really get some good workouts on.

Bas Ruten sold me this when I heard him talk about fighters getting huge boost from it. I've been doing it 5 to 7 days a week for months now while training for a marathon. One thing that bothered me about it was Bas said just 4 minutes a day but I wasn't sure if that meant 2 minutes of exercise one and 2 minutes of exercise 2 or 4 of each so I varied a bout doing it from 4-8 minutes a day. I already was pretty good at diaphragm breathing so I can't really say for certain if I got any performance increase from it. But I do think focused breath work is good for everyone to do. I did notice a few times on my long runs my lungs felt tired and it was hard to take a deep breath from using this the night before. So I stopped using it 48 hours before a long run or threshold run. I started out with the #6 covered and moved to #5 after 8 weeks. I have no idea why it comes with 15 covers when it says most people start at #5. I also found I had to keep a towel between my legs when I did it because drool started dripping out after a few minutes. In short this will give you a small increase in performance and might help you learn to use your diaphragm but Bas definitely over sold it and there's cheaper option out there. Still I got this to support him, just a little disappointed.

I was scepticall at first. After a week i did see some increase in my stamina but i waited one and a half month to be sure. Yes it does work! My stamina is a lot better. I can expand my chest more and funny enough after exercise too i actually can feel i use my back muscles when i brathe:) i cant wait what results i will get after a year or something. Highly recomended

Product was delivered on time and as expected. Have started using it now and expect to see results soon.

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.

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.

Great Product! It does exactly what it promises to do.
