Performance optimization has expanded far beyond protein powders and pre-workout supplements.
Today’s athletes are investing in sleep tracking, continuous glucose monitors, recovery boots, breathing trainers, and wearable technology to find even the smallest competitive advantage. One product that has quietly become increasingly popular among elite strength athletes is AIRWAAV, a performance mouthpiece designed to improve breathing mechanics, strength production, recovery, and mobility.
From CrossFit Games competitors and powerlifters to HYROX racers, combat athletes, and endurance competitors, AIRWAAV has become one of the fastest-growing accessories in sports performance.
But does it actually work?
Here’s everything you need to know about AIRWAAV, the science behind the technology, who should consider using it, and why performance mouthpieces have become one of the biggest trends in athletic training.
What Is AIRWAAV?
AIRWAAV is an American sports performance company that develops lower-jaw performance mouthpieces engineered to optimize tongue position and improve airflow during exercise.
Unlike traditional sports mouthguards that primarily protect teeth, AIRWAAV is designed to become an active performance tool.
According to the company, its patented mouthpiece aims to improve:
- Strength
- Power output
- Endurance
- Breathing efficiency
- Recovery
- Mobility
- Athletic stability
The company also recently expanded into recovery products with the RX1 Recovery Mouthpiece, designed to support overnight breathing and sleep quality without repositioning the jaw like many traditional sleep devices.
How Does AIRWAAV Work?
The concept is surprisingly simple.
The mouthpiece fits over your lower teeth and encourages a specific position of the jaw and tongue.
This positioning is intended to:
- Open the airway
- Improve breathing efficiency
- Enhance neuromuscular activation
- Create a more stable brace during heavy lifting
Rather than simply protecting your teeth, AIRWAAV is designed to influence the way the body breathes and stabilizes under load.
The company calls this its patented airway optimization technology and says it is supported by more than 15 years of research.
The Science Behind AIRWAAV
One reason AIRWAAV has attracted attention is its emphasis on published research.
The company highlights studies led by exercise physiologist Dr. Dena Garner, whose work has examined how lower-jaw oral appliances may influence breathing, neuromuscular function, and recovery.
According to AIRWAAV, research has demonstrated potential benefits including:
Reduced Respiratory Rate
Studies cited by the company found respiratory rates decreased by as much as 20%, allowing athletes to breathe more efficiently during high-intensity exercise.
Lower Cortisol Response
One published study reported reductions in post-exercise cortisol levels of up to 50%, which could contribute to improved recovery following intense training sessions.
Increased Neuromuscular Activation
By improving jaw position and allowing athletes to create stronger bite pressure, AIRWAAV may enhance muscle recruitment during explosive movements.
Improved Mobility
Reduced muscle tension around the neck and jaw may allow better rotational movement and overall mobility during athletic performance.
While these findings are promising, it’s worth noting that independent research on performance mouthpieces remains relatively limited, and broader scientific consensus is still developing.
Who Uses AIRWAAV?
One reason AIRWAAV has grown quickly is its adoption across multiple sports.
The company works with athletes from:
- CrossFit
- HYROX
- Powerlifting
- Olympic Weightlifting
- MMA
- Wrestling
- Functional Fitness
- Football
- Baseball
- Endurance Sports
Professional strength athletes including Jesus Olivares and Jennifer Thompson have publicly endorsed the product, while numerous CrossFit and HYROX competitors also use AIRWAAV during competition and training.
AIRWAAV Performance Mouthpiece vs Traditional Mouthguards
Most athletic mouthguards focus on one objective:
Protecting teeth.
AIRWAAV attempts to go further by positioning the jaw and tongue to improve breathing mechanics and body positioning.
| Traditional Mouthguard | AIRWAAV |
| Tooth protection | Tooth protection plus performance focus |
| Upper or lower fit | Lower jaw design |
| General protection | Airway optimization |
| No performance claims | Research-backed performance claims |
| Standard sports use | Strength, endurance, recovery, mobility |
AIRWAAV RX1: Bringing the Technology to Sleep Recovery
AIRWAAV has expanded beyond the gym with the RX1 Recovery Mouthpiece.
Instead of focusing on athletic performance, the RX1 is intended to support:
- Better breathing during sleep
- More restorative sleep
- Overnight recovery
- Airway support without moving the jaw
Unlike mandibular advancement devices used for some sleep disorders, AIRWAAV says the RX1 works by gently encouraging the tongue forward while avoiding jaw repositioning. The company also emphasizes that the RX1 is not a medical device and should not be used to diagnose or treat medical conditions such as sleep apnea.
Why Airway Optimization Has Become a Major Trend
One reason AIRWAAV has gained momentum is that breathing has become one of the hottest topics in sports science.
Athletes are increasingly investing in:
- Nasal breathing
- CO₂ tolerance training
- HRV monitoring
- Sleep optimization
- Respiratory muscle training
- Oxygen efficiency
Companies like Oura, WHOOP, Eight Sleep, Hyperice, and AIRWAAV all approach performance from different angles, but they share the same goal: improving recovery and helping athletes perform better by optimizing physiology rather than simply training harder.
For many athletes, airway health has become another variable worth optimizing.
Does AIRWAAV Actually Work?
The answer depends on what you’re expecting.
If you’re hoping for an instant 50-pound increase on your squat, AIRWAAV probably isn’t going to deliver that.
However, many athletes report benefits such as:
- Better bracing
- Stronger bite during heavy lifts
- More comfortable breathing
- Improved confidence
- Reduced jaw fatigue
- Greater stability
Community discussions are mixed. Many lifters say the mouthpiece helps with bracing and protecting their teeth during heavy efforts, while others feel the performance gains are modest or difficult to separate from placebo effects. Even skeptics often acknowledge its value as a protective mouthpiece.
As with many performance tools, individual results vary depending on the athlete, sport, and training style.
Who Should Consider AIRWAAV?
AIRWAAV may be worth considering for:
- Powerlifters
- CrossFit athletes
- HYROX competitors
- Olympic weightlifters
- Football players
- Baseball players
- Wrestlers
- Combat sports athletes
- Functional fitness competitors
- Anyone who regularly performs heavy resistance training
It may also appeal to recreational gym-goers who want additional tooth protection while experimenting with performance-focused equipment.
The Future of Performance Accessories
Athletic performance is becoming increasingly data driven.
Instead of relying solely on harder training, athletes are now optimizing every variable possible:
- Sleep
- Nutrition
- Recovery
- Breathing
- Wearables
- Mobility
- Stress management
AIRWAAV fits squarely into this broader movement. Whether it becomes a long-term staple or remains a niche tool, it reflects a growing interest in performance products grounded in biomechanics and physiology rather than traditional supplementation alone.
As more research emerges, airway optimization and neuromuscular performance may become an even bigger part of elite training.

Final Thoughts
AIRWAAV has carved out a unique position in the sports performance market by combining mouth protection with claims around breathing efficiency, recovery, and athletic performance. Backed by years of research and adopted by athletes across strength and endurance sports, it represents a broader shift toward optimizing every aspect of human performance.
Whether you’re chasing a new personal record, preparing for a HYROX race, or simply looking for another recovery tool, AIRWAAV is one of the more interesting performance accessories to watch in 2026.
