People from all walks of life are having a great experience and experiencing fantastic results using the o2 LungTrainer ! Read below and visit www.O2LungTrainer.com
“I bought the Bas Rutten O2 lung trainer instead of the high altitude trainer. I am very impressed! This O2 lung trainer is very high quality. The unit is made of a high grade polymer coated in a biodegradable rubber housing. The mouthpiece is sort of a snorkel or scuba design and is very durable. There are two ways to use the O2 trainer: with your workout or with Breathing exercises. The trainer has an intake on the right and an expeller on the left. The intake can be adjusted . The breathing exercise screens are very challenging. Bas has online tutorials on YouTube.com/O2LungTrainer and on his website that explains everything about the trainer.
How to change the screens, what breathing exercises to do when using the lungtrainer, ect. This is the only lungtrainer I have found that works your diaphragm as well as increasing your lung capacity and anaerobic endurance. The entire case is less than half the size of a high altitude training mask and fits nicely in a book bag or gym bag. The shipping is very prompt; I had it in 4 days. Deserves six star but I can give it only five!”
