You brace
with everything. Except this.
You've dialed in your belt, your shoes, your bar speed. But the clench you already do at the bottom of every max effort is leaving force on the table, because your bite is incomplete. AIRWAAV turns it into more.

As seen in
Your jaw is the most underused muscle in your setup.
You already know the drill: big breath, brace hard, lock your whole body into one rigid column to transfer everything into the bar. But here's what almost no lifter is told. When you clench, your back molars usually never fully make contact. Your bite is uneven and incomplete.

Your bite
An incomplete clench means you're firing only part of the force your nervous system can actually send.
Clenching helps. Clenching on AIRWAAV helps more.
There's a peer-reviewed phenomenon called concurrent activation potentiation: a maximal jaw clench sends a surge of neural drive that overflows into the muscles doing the work, recruiting more motor units, faster, for more force exactly when you need it.
1
Full molar contact
The patented bite plate is engineered so every tooth, especially your back molars, makes full, even contact when you clench.
2
Greater neural drive
That complete clench accelerates your neuromuscular response, sending a stronger signal to the muscles doing the lift.
3
More force output
More motor units firing means more force and a better shot at grinding through your sticking point.
Why the bite plate is the whole thing.
For most people, biting down is front-loaded and uneven, and the back molars barely touch. AIRWAAV's bite plate was engineered through 15+ years of research and dozens of iterations so your whole bite makes contact at once. That complete, even clench is what drives the effect.
Watch the clench fire faster.
A hard clench on AIRWAAV speeds up the signal from your nervous system to the muscles doing the lift. Here's what that looks like.
"Can't I just bite down on a $10 mouthguard?"
No. And the difference is the whole point. A drugstore boil-and-bite molds to your existing, uneven bite. It locks in the same incomplete clench you already have.

You're not buying a mouthguard. You're buying the bite.
The strongest lifters don't go in without it.
"It allows me to stay tight while in the process of producing intrathoracic and valsalva pressure. The AIRWAAV has enough substance to protect my teeth and alleviate neck and jaw pain caused by the need to clench your teeth to develop this pressure."

"AIRWAAV has become as important to me as my knee sleeves or lifting belt. It is part of my gear that I can't do without."

"AIRWAAV helps me stay tight and focused as well as protect my teeth when gritting them together when grinding a lift."

It's the same physiology either way. The clench you brace with under a max squat is the exact mechanism the top strongmen rely on under their heaviest loads. The force effect holds up across the whole strength world, including under your bar.
Thousands of lifters have already made the switch.
Men and women, raw and equipped, garage gyms to national platforms. The AIRWAAV is showing up in setups everywhere.

Join thousands of lifters training and competing on AIRWAAV.
15+ years of peer-reviewed work.
Developed with Dr. Dena Garner, a leading researcher in muscle physiology and airway performance at The Citadel. The force effect of jaw clenching is published science, not a marketing claim.
Force & RFD
Peer-reviewed research found that maximal jaw clenching improved peak force and rate of force development during an isometric pull. That's exactly what carries you through a sticking point.
50%
lower cortisol
A secondary benefit for your training as a whole: in a peer-reviewed study, mouthpiece use reduced post-exercise cortisol by up to 50%. That means a lower stress response and better recovery between heavy sessions.

Your enamel will thank you, too.
Every time you clench through a heavy max effort, there's a barrier between your teeth taking the load, so the grind of a one-rep max isn't going straight into your enamel. Most lifters don't buy it for this. It's just a good reason to keep wearing it.

Mold it, take it into your next heavy session, and judge it by your own brace and your own numbers. If it's not the difference you hoped for, you can send it back.
Questions lifters ask first.
Is this legal in competition?
AIRWAAV is a mouthpiece, not a supportive device like a belt or sleeves, so it doesn't fall under supportive-equipment rules. Check your specific federation's mouthguard policy, but lifters compete in it across federations, including world champions.
PX1 or PX2 for powerlifting?
Most powerlifters prefer the PX2. It's the snug, locked-in fit that doesn't move when you clench hard. PX1 is a lighter, open fit. Start with PX2 for max-effort work, or try the Hybrid pack with both mouthpiece models.
Won't a $10 mouthguard do the same thing?
No. A cheap boil-and-bite molds to your existing uneven bite and locks in the same incomplete clench. The patented bite plate is engineered for full, even tooth contact, especially the back molars, which is what actually drives the force effect.
Will it mess with my breathing or my brace?
No. It's low-profile and sits on your bottom teeth, out of the way. It's designed to let you breathe and hit your brace normally. Most lifters forget it's in within a session.
How do I fit it?
Heat it, bite to mold it to your teeth, and it's ready the same day. No dentist, no impression kit. A few minutes start to finish.
Does it actually protect my teeth?
It adds a barrier between your teeth when you clench under heavy load, which many lifters find eases the jaw and tooth strain of hard max efforts. We don't position it as a dental guarantee, but it's a benefit lifters mention often.
Stop leaving force on the bar.
Turn the clench you already do into more force, a tighter brace, and a better shot at the lift you've been stuck under. Mold it tonight.
