Testimonials

Health & Well-being, Working Professional

Have been using the O2 trainer and it has been great to use, noticed after first week huge improvement in my cardio that now when I do physical labor in the oilfield I do not feel as winded. Heard Mr. Rutten discuss his product on Joe's podcast when he was on and thinking of making it. Just made me eager to try it out, after hearing of his asthma attacks and knowing people with similar, but not as bad conditions, knew that he put alot of thought into his product. Great guy looking forward to Here Comes The Boom and watching Inside MMA. Much love and respect for Mr. Rutten - powerful.

Fighter + Weight Loss

For the last 4 to 5 weeks before the use of the trainer I lost 1 lbs. The week that I have implemented the O2 Trainer I lost 3 lbs. I noticed more calories being burned, higher intensity on workouts, more sweat, and longer periods for heart rate to come back down. After creating a base line and looking at my numbers doing the same workouts I do see an increase of calories burned and so on. I am down to 209lbs from last week’s weigh in. Only 10lbs more to break under 200 again.

Dear Bas Rutten,

I wanted to tell you how impressed I am with your O2 Trainer. Since purchasing it, I have used it with my Krav Maga training. I have also used it with the Bas Rutten MMA Workout. What a challenging workout when combined with the O2 Trainer!! I have noticed remarkable gains in my stamina in just a short time with the O₂ Trainer. This device will definitely be an item that I will train with for years to come.

Thanks for making such an excellent product!
