## Features

- THE OFFICIAL BAS RUTTEN RESPIRATORY TRAINING DEVICE - Designed by Bas Rutten himself to increase inspiratory (inhalation) muscle endurance, the O2 Trainer is a lightweight breathing device that regulates air intake and improves muscle oxygen efficiency during exercise.
- RESULTS AFTER ONLY 30 DAILY REPS - The O2 trainer is more than just a tool for athletes to improve their training. In just under four minutes of work, 30 reps with the O2 will strengthen your lungs and breathing muscles in your upper abs. Training your breathing in this way benefits your everyday life!
- STRENGTHENS YOUR LUNGS AND DIAPHRAGM - The O2 Trainer controls air intake to the lungs and supports the shift in your breathing to your diaphragm. Red blood cell concentration increases, maximum cardiac output decreases, the volume of air ventilation in muscles improves… all from a fitness breathing mask that reduces in-workout stress and anxiety.
- PORTABLE KIT DESIGN – Both the trainer and the inserts have been designed to fit in an easy to pack portable kit. The O2 kit fits in any gym bag or suitcase, making it easy to train on the road just as easily as when you’re home.
- LOVE IT OR YOUR MONEY BACK - If you feel for whatever reason that the power O2 Trainer doesn’t instantly improve your in-workout breathing and the quality of your exercise, let us know and we will refund your purchase within the first 30 days with no questions asked.

    Big improvement in overall stamina
  

*by R***R on Reviewed in the United States on February 9, 2018*

So far I'm a big fan of this. I have yet to use it during a physical activity but have been using with the standard stationary breathing exercises and have noticed a big improvement in my breathing stamina. I was a smoker for years and really did a number on my stamina. I quit 3 years ago and just thought I did irreversible damage and I would just have to deal with my breathing the way it was. This has definitely helped to prove me wrong. I recommend this to anyone that has quit smoking and is looking to build back up their stamina.

    Saved my life
  

*by S***S on Reviewed in the United States on March 21, 2017*

This is an incredible product.10 stars if I could!This helped with an old martial injury: scars in the lungs.I spent years in agony. Limited by my lungs being filled with calcified tissue.This tool strengthened my diaphragm. Opened up the remainder of my functioning lungs.Expanded my ability for long term cardio. Months later, I am a leaner man.Now, I use this o2 trainer for meditation and deep "tummo" practice.There is nothing quite like this tool, if you use it properly.Thank you, Bas.I write this with tears in my eyes. $50 and my life was forever improved.Thank you.

### ⭐⭐⭐⭐⭐ 







  
  
    100% worth it.
  

*by J***N on Reviewed in the United States on October 16, 2017*

After about 3 miles, my back doesn't like running so much so I wanted to use this to maximize my cardio within 1.5-2 miles. It's amazing. I feel like it's working.Before I work out with it, I'll throw the smallest one on while I drive to the gym and change. Sometimes I'll wear it around the house while I'm cleaning and stuff. The nose piece expands slightly but it's really not that big of a deal.
