How the AIRWAAV Performance Mouthpiece Is Changing the Way Athletes Breathe, Lift, and Recover
When most lifters think about performance gear, they think about straps, belts, or shoes—not mouthpieces. But if you’ve ever caught yourself clenching your jaw during a heavy lift, you’re not alone. That intense grind that comes with pushing through a set of squats or deadlifts can take a toll on your teeth over time. I learned this firsthand when my dentist pointed out the signs of wear from years of training. That conversation sent me looking for a solution and eventually led me to AIRWAAV, a company that’s redefined how athletes think about performance mouthpieces. In this AIRWAAV Performance Mouthpiece review, I’ll break down how it helps improve breathing efficiency, protect your teeth during training, and enhance overall gym performance.
Trusted by over 80% of the world’s top Strongman competitors, AIRWAAV has become one of the most recognized performance gear brands in strength sports. Athletes such as Mitchell Hooper, Trey Mitchell, and Tom Stoltman all use AIRWAAV in training and competition. I put both the PX1 and PX2 mouthpieces to the test to see how they stack up for everyday training and heavy lifting.
About AIRWAAV – The Science Behind the Bite
The Science-Backed Mouthpiece Trusted by 80% of the World’s Strongest Athletes
AIRWAAV isn’t your average mouthguard company. The brand was developed through collaboration with Dr. Dena Garner, a researcher and professor who has spent over 15 years studying the connection between jaw positioning, breathing, and athletic performance. Her research led to a patented design that optimizes the alignment of your jaw and tongue to improve airflow, reduce cortisol levels, and enhance endurance during physical exertion.
This scientific foundation is what separates AIRWAAV from traditional boil-and-bite guards. These mouthpieces aren’t just about protecting your teeth; they’re designed to help you perform better by improving oxygen efficiency and focus while reducing clenching-related strain. It’s no surprise that elite athletes across powerlifting, CrossFit, and Strongman have made them a staple in their training arsenal.
Design and Features of the AIRWAAV PX1 and PX2 Performance Mouthpieces
AIRWAAV currently offers two performance models: the PX1 and the PX2. Both are custom-moldable using a simple boil-and-bite process and made from medical-grade, BPA-free materials. Each is engineered around the same neuromuscular science but built for slightly different types of athletes.
The PX1 Performance Mouthpiece is designed primarily for strength and power athletes. It fits on the lower teeth and positions the jaw in a relaxed state, helping to reduce clenching and improve muscle stability. During heavy compound lifts, the PX1 creates a natural, controlled bite that feels comfortable yet secure. The design also allows for easy hydration without removing the mouthpiece, something that instantly stood out to me after years of dealing with bulky guards that had to come out every time I took a sip of water.
The PX2 Performance Mouthpiece takes a slightly different approach. It sits a bit higher and offers a thinner profile that’s better suited for longer training sessions, endurance work, or conditioning. The PX2 encourages a more open airway, allowing for smoother breathing during sustained efforts. It’s an ideal fit for anyone doing hybrid training, high-intensity intervals, or Strongman events that require both power and endurance.
Both mouthpieces share the same mission: to help athletes breathe better, perform longer, and recover faster. The difference really comes down to personal preference and training style.
My Experience Using the AIRWAAV Performance Mouthpieces
As a long-time bodybuilder, I’ve always been aware of the little habits that show up under the bar—tight grip, controlled breathing, focused mindset—but I never realized how much I was clenching my jaw until my dentist pointed it out. Years of grinding my teeth during lifts had started to leave visible wear. So, like most of us would, I tried the cheap “Amazon specials,” those old-school, bulky guards that feel like you’re chewing on a rubber puck. They were uncomfortable, made it nearly impossible to talk, and every time I tried to drink water mid-workout, I’d have to take them out. Not exactly ideal when your hands are covered in chalk and sweat.
After we interviewed Mitchell Hooper back in April, he suggested I try the AIRWAAV Performance Mouthpiece during my own workouts. If the World’s Strongest Man swears by it, I figured it was worth a shot. I tested both the PX1 and PX2 models over several weeks of training, covering everything from heavy leg sessions to conditioning circuits, and the difference was immediately noticeable.
The first thing that stood out was comfort. The fit was snug but not intrusive, and once molded properly, it stayed in place naturally. Breathing felt smoother, especially during longer sets, and the subtle jaw alignment seemed to take tension off my neck and shoulders. Both models performed well, but personally, I gravitated toward the PX1. The relaxed lower-jaw position felt ideal for heavy training, and I loved that I could drink water mid-session without having to take it out. No more awkward pauses or touching dirty equipment to remove a mouthpiece. Small detail, big difference.
That said, the PX2 deserves its praise. I found it especially useful during longer, higher-volume workouts where consistent breathing and endurance come into play. It’s easy to see why endurance athletes and Strongman competitors who train for hours at a time prefer that style. In the end, it really comes down to which one feels best for your type of training.
Performance Benefits of the AIRWAAV Mouthpiece Backed by Science
What impressed me most about AIRWAAV is that it’s not marketing fluff, it’s backed by measurable research. Dr. Garner’s studies have shown that the AIRWAAV mouthpiece can improve airway efficiency, reduce cortisol levels, and even lower heart rate during exercise. The design positions your jaw and tongue in a way that helps open your airway and promotes better oxygen flow. The result? Less fatigue, greater focus, and improved recovery after intense sets.
These physiological effects make sense once you experience it firsthand. After just a few sessions, I noticed I wasn’t clenching nearly as much, which left my jaw and neck feeling more relaxed even after heavy lifting. Breathing through the mouthpiece became second nature, and it didn’t take long before it felt strange to train without it.
Final Verdict: Is the AIRWAAV Performance Mouthpiece Worth It?
After putting both versions through weeks of consistent use, I can confidently say the AIRWAAV Performance Mouthpiece deserves its reputation. It’s not just another gym accessory. It’s performance gear that genuinely enhances the way you train. The combination of comfort, science-backed design, and real-world results makes it one of the most worthwhile additions to any serious lifter’s toolkit.
Whether you choose the PX1 for its relaxed fit and heavy-lift focus or the PX2 for its endurance-driven design, both deliver what they promise: better breathing, better performance, and better protection. Once you experience the difference, it’s hard to imagine hitting a PR without it.
