Congratulations on your O2IN trainer purchase!

What Is O2IN?

O2IN is a state-of-the-art device that lets you train your respiratory muscles on the go.

Who Is It For?

  1. Anyone who wants to enjoy comfortable breathing in an urban environment and keep in sync with city life: breathe in deeper, cover familiar and/or large distances faster and without getting short of breath, and facilitate faster recovery after sickness.
  2. Anyone who is into sports and is looking to increase their performance during training.
  3. Anyone who seeks to increase their blood's oxygen consumption in order to stimulate better collagen production and enhance skin elasticity as a result.
  4. Anyone who places expressed importance on preventive measures for myocardial infarctions or strokes and is looking for efficient asthma treatments.
  5. Children and teenagers.
  6. Professional athletes that set their bars high and aim for the best result possible.
How Does O2IN Work?

The idea behind the O2IN trainer is based on three major principles:

- Resistance to expiration of air
- Vibration of expired air
- Intensity of movement
The trainer is designed in the manner that lets you breathe in through your nose and mouth equally easily.

As you breathe out, a special mechanism creates resistance and triggers vibration. Combined, this facilitates respiratory muscle training and lung cleansing (by removing sputum).

Effects Of Using The O2IN Trainer:

  1. Respiratory muscles develop better strength and endurance thanks to their increased workload.
  2. You become capable of deeper intake and release of breath.
  3. Improved discharge and release of sputum from the lungs help cleanse them better.
  4. Airways that are usually underprovided with oxygen become more engaged in the breathing process.
  5. The lungs' vital capacity is increased and normalized.
  6. Admission of oxygen to the bloodstream and to visceral organs increases.
You will experience the lifting of chronic fatigue and find it easier to concentrate. It will also become easier to take on familiar or increased physical load.

It is advised to use the trainer during various workout and fitness sessions, as this is when it performs most efficiently.

By varying your workout intensity, you regulate the level of oxygen intake and its admission to the bloodstream, as well as the share of carbon dioxide in the air you breathe out, determining your oxygen consumption coefficient.

We recommend using some form of heart rate control, such as a pulsometer, to manage your lung load during workout.
The Package Contains:

  • The trainer and a mouthpiece
  • A silicone case
  • A textile bag for storage
  • A user manual

Using Your Trainer

Remove the packaging and study the user manual with attention to detail.
Make sure to thoroughly wash the trainer under running water before use.
You can use the trainer both with and without the case. It is common to experience increased salivation and discharge of sputum during the first few training sessions as you get familiar with the process, so we recommend using the trainer with the case, as it collects all excess discharge and makes using the trainer more comfortable.

Remember that the trainer is your personal device; do not let others use it without replacing the mouthpiece and thoroughly cleaning the entire device by washing it under running water for several minutes.

You will experience salivation, as well as sputum and mucus discharge during training, so make sure to wash the trainer thoroughly under running water after you're done.

Store your trainer in the special bag provided in the package.

You are highly disadvised to use your O2IN trainer outdoors when temperatures are below 3-5°C. This may provoke adverse medical conditions of the throat and airways.
Configuring Your Trainer

The trainer requires no special configuration for you to begin your session.

Place the trainer in the manner so that you can read the O2IN wording. Do not flip it to ensure correct inhalation and exhalation.

Now, try to breathe out through the trainer; you will hear a low sound and experience vibration as you do. You will also sense certain air resistance.

If you are planning on using the trainer in a non-standard position (say, you are on a treadmill, and the TV screen you are looking at is placed in front of you, but higher than your eye level), open the side cover and shift the lever from 30 to 50. If you are lowering your head down during training, shift the lever from -20 to -10.

That's it! You're all set to train.

Don't forget that the trainer facilitates the cleansing of your lungs, which may result in increased salivation and sputum discharge as you train; during expiration, all excess substances are released through the valve outside or into the case, if you are using it. In the rare case that there is too much saliva or sputum, you will be best off removing the mouthpiece from your mouth and spitting out the excess.

Here you go: your trainer is ready for use.

So, let's get to the actual training!
Training Program

Here is a list of possible sports and workout disciplines that are a great fit for using the O2IN trainer (of course, the list is not exhaustive):

- Outdoor running;
- Treadmill running;
- Walking;
- Cycling;
- Rowing;
- Gym training;
- Nordic walking;
- Fitness;
- Dog walking;
- Outdoor activities with family;
- Home activities (exercising, house-cleaning).

In the beginning, you must let your body get used to the "obstacle" that is in the way of its familiar breathing; especially since the trainer, due to its construction, will stimulate you to breathe in and out with greater intensity than normally, no matter how intense your workout or physical activity currently is.

And that is why we recommend that you start off by getting used to the trainer while remaining stationary. In a few minutes, try walking and waving or swinging your arms to see how that feels.


During stationary use of the trainer (i.e. when you are not moving), it is possible to experience dizziness due to the hyperventilation that may occur. In this case, please, stop your training session.

Planning your session with the O2IN trainer to work on your respiratory muscles.

Do not rush to perform your routine with maximum output for the first few times that you are using the trainer. It is essential to get used to breathing through it first.

If you are a beginner, your recommended O2IN training time during your overall workout session or circuit is 15 to 20 minutes at a pulse rate of 110-120 bpm. After 4 or 5 sessions, and depending on your general condition, you can increase the time of trainer use to 20 or 25 minutes per specific routine. However, you should not use the O2IN trainer for more than 30% of the overall workout session time in total.

Now, pros should use the breathing trainer for no less than 35-40% of the overall workout session time, and at a pulse rate of 120-140 bpm.
If you train 8 to 10 times a week, you should use the O2IN trainer every other session. If you train 2 to 3 times a week, aim to use the O2IN trainer every time. The overall number of sessions with the trainer should not exceed 15 to 17; once you've clocked that, take a break and return to using the trainer during your workout session in 10 to 14 days.

IMPORTANT! Persons that are not fit for substantial physical load are forbidden from using the O2IN trainer at a pulse rate of over 120 bpm.

Examples of using the O2IN trainer during workout sessions.

- Warm up with the trainer for 2 to 3 minutes.
- Perform physical exercises (at low or medium intensity) with the trainer for 12 to 15 minutes.
- Complete the main part of the workout without the trainer for 25 to 30 minutes.

- Warm up with the trainer for 3 to 5 minutes.
- Perform physical exercises of appropriate intensity with the trainer for 20 to 30 minutes.
- Train as intended without the trainer.
