Ultrabreathe looks similar to the devices listed above. You place your mouth on an anti-bacterial, medical-grade, PVC mouthpiece, then breathe as normal. The device resists your breath, strengthening your lungs over time. You can rotate the cap of the Ultrabreathe to adjust the difficulty. Engineered to increase inspiratory (inhalation) muscle endurance, the O2Trainer is lightweight and designed to be used while performing nearly any exercise or activity. Designed for athletes and performers who depend on their lungs should be working out with the O2Trainer to increase endurance, stamina and performance. The idea behind the Bas Rutten O2 Trainer is to help increase your lung capacity. The most critical part is the lung volume which is the amount of air that you get in a single inhalation. The high the volume the better. Your body needs as much oxygen as you can get not only to burn fat for energy. Oxygen also but remove waste byproducts in the muscles. Otherwise, you start feeling tired immediately after training. High adequate oxygen levels keep your in shape for long. That is what translates high performance, especially for sportspersons.

Practice belly breathing exercises to strengthen your muscles, getting you accustomed to breathing from your diaphragm instead of your chest. Insert the trainer in your mouth and inhale through the diaphragm as hard as you can while returning to the seat position A simplified version of the Airofit PRO, provides adjustable resistance levels to your breathing muscles, primarily the diaphragm and the intercostal muscles. Don't let the simplicity fool you, this device works wonders! Engineered to increase inspiratory (inhalation) muscle endurance, the portable O2 Trainer can be used while doing nearly any exercise.Many singers, artists, and musicians use breathing trainers. Better lung capacity can improve musical performance whether singing or playing certain instruments. Acapella singers, rappers, opera singers, and others can particularly benefit from breathing trainers. If you aren’t a freediver, let alone a movie star playing a supervillian, the idea of willingly training your lungs to failure probably doesn’t sound too appealing. And considering most of us don’t have access to “Captain Kirk,” as Robbie likes to call him, messing around in the pool or ocean on your own is also downright dangerous. But the point remains — we all could be getting more air from our diaphragms if we trained them to operate more efficiently. Better yet, many people combine free breathing exercises with the products above. You can strengthen your lungs with a professional breathing trainer, then improve your lung capacity with free breathing exercises.

Breathing Retention: Inhale a deep breath and hold for as long as you can. This boosts oxygen supply and absorption. Again, if you have hypertension or heart issues, you should avoid this breathing strategy. Some pilots also use breathing trainers. Pilots can improve lung capacity with a breathing trainer, making it easier to fly at high altitudes or experience strong G-forces without passing out.

Evidence tells us breathing trainers work. Many studies have shown that breathing trainers can improve lung capacity, boost strength, raise endurance, and reduce symptoms of certain respiratory conditions.
