Bas Rutten O2 Trainer


The Bas Rutten O2Trainer is a simple device that trains your lungs as if you’re at a high altitude, and can be used while running, weight lifting, rock climbing, or performing any other exercise.

It’s adjustable to four different levels to allow you to slowly improve your inspiratory muscle endurance – in layman’s terms, lung strength. The O2 Trainer also comes with four more end caps to be used while in a resting position; so you can give your lungs and diaphragm a workout even while lying down.
