You Might Want to Hold Your Breath on This One

Back in my high school swimming days, I noticed that despite the fact that swimmers are renowned for holding their breath, my lung capacity was terrible. I could only hold it for around 45 seconds which is just about average for the normal human. But for someone who spends half of their time underwater, it was just pathetic. Scientifically, there is no real way to increase your lung capacity in terms of volume. The only thing you can do is increase the efficiency of your lungs so that they absorb more oxygen into the blood. This device does just that by simulating a method called altitude training that makes your lungs work harder for every breath. While it may look a little weird to be wearing around the gym, this thing flat out works! 

I started noticing results within my first few days of using the O2 Trainer. Before I started using the device, I could only hold my breath for 45 seconds. After about two weeks of using it, I could hold it for over 2 full minutes!. Running 3 miles felt effortless unlike before where I felt like a beached whale trying to roll back to the ocean. My true test for this item came when I tried to run my first ever 5k while only training for two weeks on our home elliptical. Never running a 5k before, I surprised myself by taking 2nd overall with ease.

How It Works

One of the great things about this product is its simplicity. When you breathe in through the mouthpiece, air has only two ways into your lungs. It can either go through one of the different sized screens or “try” and come through the universal blockage screen. Because of the way that the flap is made, it allows for resistance when Inhaling, but not when exhaling.

This is a very important point, because unlike similar products, there is resistance on both the  inhale and the exhale. What this allows is the oxygenation of the athletes muscles when they need it most. The whole point of the O2 Trainer is to train your inspiratory muscles so that they can become stronger just like your skeletal muscles. Check out the video below for Bas’ official video.


Overall, the Bas Rutten O2 Trainer works the way it was intended to and for the small price of $50, it’s really quite a steal. As long as you don’t mind washing it off after each use (as you should with any product that has been in your mouth) this item is great. If increased endurance in a short amount of time is what you’re looking for, this is the product for you.
