Official Respiratory Training from Bas Rutten

Designed by Bas himself to increase inspiratory (inhalation) muscle endurance, the O2 Trainer is a lightweight device that regulates air intake and improves muscle oxygen efficiency during exercise.


Improve Breathing Power

The O2 trainer restricts air intake to strengthen your abdominal muscles and regulates your breathing form - training your body to properly take in deeper breaths and more oxygen.

Defeat Training Fatigue

The ability to intake more oxygen and breathe properly leads to improved body composition and supports a healthy circulatory system.

Gain Lean Muscle

Change resistance levels by using one of the 14 included air intake caps. As your endurance increases, change out the intake cap to reduce airflow and increase resistance. As your air intake decrease your body will build muscle strength while learning proper form for deeper breaths.


Follow along with Bas as he leads you through a simple breathing exercise with your O2 trainer to build stronger lungs and increase your oxygen intake - all it takes is 30 reps and less than 3 minutes a day!

    I've had issues getting a full breath of air in for over 10 years due to an injury to my chest. I cannot believe how well this device has helped strengthened the muscles needed to properly breath. Best $50 I've ever spent!

    Well worth the investment

    Day 42 of the 42-day challenge with the O2 trainer. A challenge by Bas Rutten. This is designed to increase lung power capacity as well increase stomach muscles and endurance. Designed to breakdown the Lactic acid around the belly. So I decided to take it up a notch-Bas recommends 60 reps a day for 42 days if you are training for a pro fight. I did 120 reps a day. Using level 14 on the o2 device. It normally will take me if Im tired to do my normal routine anywhere from 30-35 min. When I completed this program I was able to reduce my cardio workout time by 13 min. Meaning what usually took me 35 min to complete, now only took me 22 min. My normal work out consists of 100 jumping jacks, knuckle push-ups, ab roller pushups, dips, wrestler sand crunches. As of the report today I can tell you energy level will increase issues with the lungs will improve and man do I feel like a million bucks in the inside. You will however when you start will feel the difference after a week. This is a very important tool for black people with asthma or bronchitis or COVID 19. I highly recommend using this as a defense against ailments as it increases the oxygen levels in the body which in turn helps your breathing singing and fighting skills. For less than $50 bucks your health increases a thousandfold. I highly recommend everyone over 12 use this. Day 42 -5040 reps and climbing Forgot to mention if you're into yoga this will align all your chakras and you will feel the chi energy begin to flow freely up and down your spine.
