You Found Us at the Right Time
You're here. That means something.
Maybe you stumbled across Expand-A-Lung for the first time. Maybe you heard about it years ago and are only now circling back. Maybe you’ve been training hard for a while and something keeps telling you there’s a ceiling you haven’t broken through yet.
Whatever brought you here this is the right place to start.
Expand-A-Lung has been building respiratory training tools since 2004. The mission has always been the same: make professional-grade breath training available to everyone willing to put in the work. Not just elite athletes. Not just clinical settings. Everyone.
Now we’re back with fresh energy, a sharper focus, and the same device that’s been quietly changing how people perform for over two decades.
Here’s how to use this moment. Here’s where to begin.
First: Understand What You're Actually Training
Before the drills, before the device, before any of it understand what respiratory training actually is. Because it’s not what most people think.
It’s not breathing techniques for stress relief. It’s not box breathing for sleep. Those have their place, but that’s not what this is.
Respiratory muscle training is the deliberate act of strengthening the muscles responsible for breathing the same way you’d train your legs, your back, your core. Your diaphragm is a muscle. Your intercostals are muscles. When you train under load, they fatigue like every other muscle group. When they’re weak, they become the bottleneck.
When they’re strong? Everything changes.
More efficient oxygen delivery. Less perceived effort at the same intensity. A higher threshold before breathing becomes the limiting factor. Faster recovery between hard efforts.
That’s what you’re training. That’s what this is for.
Your First Week: A Fresh Start Plan
Whether you’re brand new to respiratory training or returning after a break, start here. One week. Consistent, intentional, simple.
Day 1: Assess Your Baseline
Before adding anything to your training, spend five minutes getting honest about your breathing.
Sit quietly. Breathe normally for 60 seconds and just observe. Are you breathing through your nose or your mouth? Does your chest rise more than your belly? Do you feel your exhale is shorter than your inhale?
There’s no wrong answer here this is just data. Most people discover they’re shallow chest breathers with short, incomplete exhales. That’s exactly what we’re going to fix.
Baseline drill: Time how long you can sustain a slow, controlled, nasal inhale. Most untrained breathers max out around 3–4 seconds before reaching for more air. Note your number. You’ll come back to it.
Day 2: Build the Foundation: Diaphragmatic Breathing
Everything in respiratory training starts here. Not because it’s easy, but because it’s fundamental. Chest breathing is a habit. Breaking it takes deliberate practice.
How to do it:
- Lie flat or sit tall with your spine straight
- Place one hand on your chest, one on your belly
- Inhale slowly through your nose your belly rises first, chest stays still
- Exhale fully belly falls, squeeze the last of the air out
- 5 seconds in, 6 seconds out
- 10 rounds
Do this before your workout today. Notice how different your first few minutes of training feel when your respiratory system is already primed and activated.
Day 3: Carry It Into Training
Today, take what you practiced yesterday into your actual workout. The goal isn’t perfection it’s awareness.
Pick one specific moment during your session to consciously control your breath. A set of squats. A hard interval. The top of a hill. Choose one moment and refuse to let your breathing go reactive.
Slow your exhale. Stay nasal as long as you can. When you feel the urge to gasp that’s the rep. That’s where the training happens.
Day 4: Active Recovery Breathing
Rest day doesn’t mean breath day off. Use today to build CO2 tolerance and nervous system control.
Extended exhale breathing 10 minutes:
- Inhale for 4 seconds
- Exhale for 8 seconds
- Keep it nasal throughout
- No forcing, no strain just length and control
This feels almost too simple. It isn’t. A longer exhale activates your parasympathetic nervous system, improves respiratory efficiency, and trains your body to stay calm at lower oxygen levels which directly translates to composure under hard effort.
Day 5: Add Resistance
Now you’re ready for the next layer: breathing against resistance.
This is the principle behind the Expand-A-Lung device progressive overload applied directly to your respiratory muscles. But before the device, you can feel the principle with a simple drill.
Pursed lip resistance breathing:
- Inhale fully through your nose 4 seconds
- Exhale through pursed lips (like blowing through a narrow straw) 8 seconds, slow and controlled
- Feel the resistance build in your chest and diaphragm
- 10 rounds
This is a preview of what dedicated respiratory muscle training does on every single breath. Your diaphragm working harder. Your respiratory muscles under load. Adaptation beginning.
Day 6: Breathe Through the Hard Part (Again)
Return to training today with one goal: breathe through one more hard moment than you did on Day 3.
Stack the reps. Stack the adaptation. That’s all training is.
Day 7: Reflect and Reset
At the end of your first week, return to the baseline drill from Day 1. Time your controlled nasal inhale again.
For most people, even one week of intentional breathing practice produces a measurable difference. Not because the muscles have fully adapted yet but because awareness changes mechanics. You’ve started training something that was always there, always available, always capable of more.
This is just the beginning.
What Comes Next
A week of intentional breathing practice builds the foundation. What builds on top of it is dedicated respiratory muscle training adding progressive resistance to every breath so that the diaphragm and respiratory muscles continue to adapt and strengthen over time.
That’s exactly what the Expand-A-Lung device was designed to do. Compact. Drug-free. Built on the same principles that have driven breath training in the performance world for decades now in your hands.
You found us at the right time.
Now you know where to begin.
