Weak respiratory muscles "rob" you of up to 70% of oxygen you breathe in, having an adverse impact on the quality of life, health and the immune system.

It hinders breathing in an urban environment, causing shortness of breath and setting back any positive effects you might be expecting from sports training or beauty procedures.

Sedentary lifestyle, smoking and air pollution decrease our ability to ingest and process oxygen, while, at the same time, stress and unhealthy food habits actually increase the body's oxygen requirement.

We end up with a deadend: as you lead a lifestyle that is not healthy enough, you become less able to admit oxygen, which makes you even less healthy and thus provokes an oxygen craving you cannot quite satisfy because… well, you get the idea.

All in all, it may lead to a number of impairments typical for the 21st century, such as mental and physical fatigue, premature aging, and others.

70% of toxins built up in the body are discharged with breath
Train only 20 minutes a day while running, hiking or even walking your dog. O2IN is designed to be used on the go increasing efficiency of your activity.
O2IN is a unique breathing trainer. It helps cleanse your lungs and "buff up" your respiratory muscles.
Resistance to expiration helps "work out" the muscle tissue of the lungs, increasing their life capacity, depth of inhale and the maximum oxygen intake;

Vibrations help separate sputum and other residue from the lining of the lungs and remove those from the organism by means of "expectoration"
There is a mixed system at work here that cleanses the lungs and strengthens the respiratory system

Why train your lungs?
For comfortable breathing in an urban environment
The vibration effect provides a natural way for the lungs to expel any residue caused by smoking or ingesting polluted air, facilitating fast removal of toxins from the organism and increasing active utilization of oxygen by 8%. This, in turn, reduces the risk of oxygen deficiency and has a positive impact on cardiac performance.
For increased sports training efficiency
As a result of regular exercise with O2In, all the respiratory system divisions experience development, the lungs' muscle tissue is strengthened, and the lungs ventilation goes up. This leads to a higher efficiency of any physical training; for example, one's average distance stats over a 12-minute period go up by 22%, while the time required for a decent warmup before the training falls by 25-35%.
For faster progress during medical rehabilitation or recuperation and preventive care
The O2In exerciser speeds up recovery after seasonal cold-related conditions and can be used for preventive care and treatment of a range of pulmonary conditions, too, including asthma.
For beauty
Strong healthy lungs let you prevent oxygen deficiency in your body, which is itself a ticket to a faster rate of complex protein and hyaluronic acid synthesis and normalized production of collagen and elastin. As a result, your skin receives natural hydration and stays young and supple for longer.

Exercising with O2In increases overall blood circulation, too, including delivering better blood flow to the skin. This makes it fresher and younger and returns its elasticity and healthy glow.
For a child's healthy development
Oxygen is a multipurpose expendable during the formation and establishment of a young child's immune system, increasing the rate of production of lymphocytes, macrophages and phagocytes that are responsible for building one's immunity.

From the age of six, children can train their lungs with the O2In exerciser regularly, strengthening and developing their respiratory systems from the very beginning. This will help build a great foundation for their future health, reducing the risks of coming down with infectious and viral conditions that are such a regular occurrence in nurseries and schools.


Regular exercise with O2IN helps increase the active use of oxygen taken in and the lungs' life capacity; in turn, it improves the oxygenation of cells, buffs up the immune system, accelerates the rate of recuperation after physical activity and launches regeneration and rejuvenation processes in one's body.

20 minutes a day is enough for exercising your lungs, and you don't even have to detach yourself from your regular chores or pastimes, including fitness or running.
Oh, one more thing: you do not need to adjust your current exercise routine or create any special conditions for working out your lungs with O2IN. Any activity is great for using the trainer: from fitness, such as running, cardio, weights or circuit training, to hiking, walking the dog or even cleaning the house.
The practical framework of using O2IN has been tried and tested over the course of ten years that it has been popular among professional athletes. Clinical studies have verified its safety and efficiency.
