FITAIR PRO 2.0
Made to enhance your breathing
The PRO 2.0 is the next evolution of our best-selling breath trainer, built for the moment your lungs give out before your legs do. Whether you're chasing a new mile time, going three rounds without gassing, or just trying to keep pace in your next workout, your breathing muscles are the limiting factor most people never train.
Powered by Dual-Resistance Training Technology, a precision system that lets you build inhale and exhale strength independently, so every session targets exactly where your breathing actually breaks down.
This isn't a gimmick or a wellness trend. It's a training tool that works the same way strength training works for any other muscle group, and it's why serious athletes and everyday people alike are using it to close the gap between how hard they train and how far their breathing lets them go.

ABOUT
Ryan Ellis
"As a cross country coach, I see countless athletes hit walls they can't seem to overcome. FITAIR is the simplest, easiest, most effective way to strengthen the breathing muscles. Stronger more efficient breathing means more endurance to train harder and run farther. Breath training is no gimmick. It's like simulating a 10 mile run in 10 minutes. One of the only "fitness hacks" that actually works. I've read through the research. I use it myself. But more importantly, I see the results first hand everyday. If you are serious about your performance then it would be foolish not to take advantage of the benefits of breath training. The team at FITAIR are pros. Great product and knowledgeable staff. Can't recommend them enough."

HOW FITAIR WORKS
How 5–10 minutes a day changes your ceiling.
Dual-Resistance Training
The PRO 2.0 lets you adjust inhale and exhale resistance independently, not locked to one fixed setting like most trainers. Every session targets the exact muscles that give out first, so your training actually matches where your breathing breaks down.
Lower Oxygen Cost
Your respiratory system can burn up to 20% of your total oxygen during intense effort. Stronger breathing muscles need less oxygen to do the same work, freeing up more oxygen for your legs, arms, and working muscles instead of your lungs.
Delayed Fatigue Response
When breathing muscles fatigue, your body reflexively pulls blood away from your limbs to protect your breathing, a response called the metaboreflex. Training delays this reflex, so you keep more blood flow, and more power, where you need it.
Built for Every Level
Start at low resistance and progress at your own pace. Just 5–10 minutes, 4–7 days a week is enough to see change, whether you're a first-time user or a competitive athlete looking for an edge.
PUSH PAST YOUR LIMITS
Finally push past that wall that’s been holding you back. FITAIR helps you train the muscles behind every breath, so you can perform stronger, recover faster, and breathe easier in every workout.
Muscle & Fitness 2025
In 2025, the FITAIR team sat down with Muscle & Fitness for an in-gym feature on breath training and its role in athletic performance. We walked through the mechanics behind the PRO 2.0, demonstrated a live session on the gym floor, and answered questions about how respiratory muscle training fits into a serious training program. It was a chance to show, not just tell, what stronger breathing actually looks like in practice.
TRAIN THE SAME, PERFORM BETTER
Same workouts. Same effort. The only difference is what's happening in your lungs.
Endurance
Stronger respiratory muscles delay fatigue, so you hold your pace longer before you break.
Recovery
Better oxygen efficiency means faster recovery between sets, rounds, or intervals.
Oxygen Efficiency
Less oxygen wasted on breathing means more available for the muscles actually doing the work.

As someone who's dealt with asthma my whole life, this has genuinely changed how I feel during workouts. Wasn't expecting that.

Didn't think a 5-minute breathing exercise could actually make a difference, but three weeks in and I'm noticing it on every run. Wish I'd started sooner.

Simple, no batteries, no app needed. Just works. My cardiologist actually recommended something like this and I'm glad I found FitAir.
