Review: Excellent tool - This is a piece of equipment everyone should have yet don't realize they need. This is probably my fifth or sixth I have purchased for myself and family members. It is gaming change in training how you breath. Well built device. A must buy.
Review: Secret Weapon - For any athlete, it is bad to have shallow and dysfunctional breathing in your chest. I compete in Jiu Jitsu and I hate the feeling of being in a hard match and my chest just starts to feel heavy like my lungs cannot possibly get enough air. For any athlete, powerful lungs are important. The first thing I started to notice with this product is that I actually had to re-teach myself how to breathe, then I noticed my lower back, upper back, core, neck, hips and even shoulders are all tight and are restricting proper breathing. When I use this product I not only feel all of the muscles associated with breathing being worked but my lungs are also pushed to their limits with capacity and all of my tight muscles that restrict my breathing are getting stretched out and becoming loose. Now there are muscles all over my belly that are going through hypertrophy, they seem to be muscles that I have not worked to such a far extent before. My recovery time in Jiu Jitsu training is faster, I can go harder, I can push the pace and go beyond what I was capable of before and on top of that I can feel myself breathing differently to the point where I even feel some of those tight muscles on my torso getting stretched out hard. I’m definitely gonna keep using this until I have full mastery, I know my stamina will be so much better than it is now.

## Questions & Answers

**Q: So using this thing at a gym on the treadmill isn't very practical due to the saliva buildup?**
A: Steven, this is Bas, how are you doing? If you keep training with it the saliva build up will get less. Some people experience this, other experience a dry mouth (They will be good after a few weeks as well)But, we are coming out with a different mouthpiece since some people can't swallow with the o2trainer in their mouth, the new design will help with that. Also, we are coming out with new tests that will blow everybody away, really great things coming. For now I want you to do the same as what I do, take 30 deep breaths with the o2trainer on level 9 or 10. Sit dow, lean over, completely exhale (everything out) then explode with breathing in while you are sitting up (you can simply press the o2trainer against your mouth while doing this). Then go down again and exhale everything and repeat 29 times.This will take about 4 min. Do this for 6 weeks in the morning and evening, after 6 weeks one time a day will be fine. The result you get will be amazing, your core will get a huge workout as well, please try it out. I will come out soon with all the tests. Godspeed

**Q: What is the maximum resistance setting in cm H20 for the blue and the green product?**
A: Both colors are identical in how they work. It's 1mm, I (I am Bas) have been doing it for 5 years straight, everyday, I use setting 1.5mm. Doing setting 1 the correct way, it extremely hard. I used to do it in 2:15m (30 repetitions) but then realized I wasn't completely inhaling and exhaling, so when I made my technique perfect, it took me over 6 min. Do NOT focus on getting to the smallest size, focus on technique, its much more effective doing it correctly. I know you just asked for the size, but I just wanna mention this because pretty much many tell me they do setting 1, which when done correctly, I find very hard to believe. Godspeed!

**Q: Does this fit children (ages 9-11?)**
A: It's very young, I am sorry but you have task your doctor. I believe with supervision from a parent who makes sure they don't push too hard should be OK. But kids at that age are still developing, so please ask your Doctor. Tell him it's a device that controls the air intake, and that YOU can control the resistance, meaning, you would make sure they don't use lot of resistance. Thank you for your interest!

**Q: so is it 4 sets of 30 reps,4 sets of 12,or 30 reps for 4 mins? some please explain.**
A: There are videos on the official website for it. There are two different exercises now. A different routine too. Now it's pick the attachment and when you can do 30 reps under 3 minutes you move to the next smaller attachment and continue like that. No more sets and your really need to go watch the videos.
