Insert the trainer in your mouth and inhale through the diaphragm as hard as you can while returning to the seat position Change the intensity of the O2 by increasing or decreasing the restriction of airflow with the screen inserts provided. Start with the 13MM screen and as endurance increases, decrease the size of the insert - it's that easy! There are four additional screen inserts that can be used while at rest. Whether you're standing, sitting, or lying down, you can still exercise your lungs and diaphragm, with the Bas Rutten O2 Trainer. When you can do 30 reps without going past 3 minutes, it is a sign your muscles have strengthened, so you can move on to a shorter cap and work harder to inhale air After a thirty rep session for five weeks, the RMT had significantly improved intermittent exercise performance of one athlete group as compared to the review group that took no RMT. Respiratory Muscle Endurance Training in Chronic Obstructive Pulmonary Disease: 1999

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. That’s why many great fight champions today, whether it’s MMA, Boxing, Thai Boxing or Martial Arts in general, use some form of breathing training device – and the O2 Trainer is a compact device with big results! Proper breathing can improve performance, build, and the overall health of an athlete. Those gains will be more marginal in over-the-top elite athletes, who were likely born with top-notch oxygen distribution systems, but for someone looking to breathe a little easier — whether while crushing a marathon or just walking up the stairs — a breathing trainer is something to consider. 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! The cumulative effect is that your strained breathing increases the resistance of these breathing organsThe Elevation Mask is also designed for helpful exercises in inspiratory endurance the same way as the O2 mask.

The study divided college soccer athletes into two groups. One used commercially available mouth RMT devices during off season, while the other continues with the usual practice exercises.

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! The O2 is a compact breathing device designed by Bas Rutten to enhance inspiratory muscle endurance. O2 Trainer 2.O Simple and Effective – Make Every Breath Count. Regulates air intake and improves muscle oxygen efficiency during exercise, 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.
