Description

NESLEMY™ LungFit Trainer is a handheld respiratory muscle trainer (RMT) with a built-in sprometer. By breathing in and out through the device, your lungs and diaphragm are exercising— like lifting weights for your breathing muscles. Over time, this helps expand lung capacity, improve oxygen efficiency, and support better overall respiratory health.

It features a built-in spirometer that allows you to measure your lung capacity so that you can see your progress over time.

The device is compact, drug-free, and requires no batteries or fans to function during training — making it safe, quiet, and easy to use anytime, anywhere. Whether you're looking to build stamina, recover from pulmonary damage, or simply breathe better, the Inex-Air makes every breath count.

What Can The NESLEMY™ LungFit Trainer Do For You?

Lung Recovery & Wellness

Whether you’re bouncing back from a sickness, shaking off a habit, or dealing with ongoing breathing struggles, breath training can turn things around. It helps get your lungs working better, builds up your stamina, and makes sure every breath counts—so your body uses oxygen like a pro. That’s where Inex-Air comes in: a natural, drug-free way to rebuild your breathing strength, no shortcuts.

  • Backing Lung Recovery: Strengthen those tired respiratory muscles, so air flows smoother and you can keep going without wearing out.
  • Boosting Oxygen Use: Make your lungs more efficient—so daily stuff feels easier, and your long-term health gets a real lift.
  • Clearing & Toughing Up Airways: Train your breath to handle CO₂ better, so deep, easy breathing becomes second nature.

Take hold of your breath. Take hold of your health.

Athletes & Fitness Enthusiasts

Serious athletes know: VO2 max—how much oxygen your body can use at peak effort—is the name of the game when it comes to endurance, speed, and bouncing back strong. That’s where Inex-Air steps in. It builds up your respiratory muscles, cranks up oxygen efficiency, and boosts your ability to handle CO2, so you can:

  • Train your lungs to soak up more oxygen and shuttle it to your hardworking muscles—hello, peak performance.
  • Nail Breath Control: Strengthen that diaphragm to cut down on huffing and puffing, and keep your stamina in the green longer.
  • Recover in a Flash: Speed up lactic acid breakdown and slash oxygen debt, so you’re ready to go hard again, sooner.

Breathe like the pros. Perform like a champ.

Musicians & Vocalists

For singers and instrumentalists alike, nailing breath control is the bedrock of it all—whether you’re belting out powerful vocals, nailing precise wind instrument riffs, or keeping your energy up through a long set. That’s where Inex-Air comes in. It hones your diaphragm strength, expands your lung capacity, and fine-tunes your airflow, so you can take your craft to the next level.

  • Step Up Your Breath Support: Strengthen that diaphragm control to nail richer, more polished vocal projection—no more straining.
  • Boost Lung Capacity: Train to hold those longer phrases, sustain notes like a pro, and keep airflow steady, no matter the piece.
  • Crush Stamina & Recovery: Cut down on huffing and fatigue, even during marathon rehearsals or back-to-back performances.

Nail the breath, nail the control, nail the performance.

Stress, Anxiety, & Holistic Wellness

Breathing is that magic link between your mind and body—and when you get it right, it can dial down cortisol, ease anxiety, and make you feel all-around better. That’s where Inex-Air fits in: it helps you master your breath, so you gain more control, stay present, and unwind like a pro.

  • Fire Up Your Vagus Nerve: Kickstart your body’s built-in relaxation mode to lower stress and slow that racing heart.
  • Balance CO₂ & Oxygen: Get your respiratory system working smarter, so you focus better, lift your mood, and sleep like a rock.
  • Strengthen Mind-Body Vibes: Use intentional breathing to boost meditation, clear your head, and keep those emotions steady.

Less stress. Sharper focus. Breathing that justworks.

    Frequently Asked Questions

    ❓What is the NESLEMY™ LungFit Trainer

    The NESLEMY™ LungFit Trainer is an RMT device—short for Respiratory Muscle Trainer. Basically, it’s a tool that makes you breathe against gentle resistance, kind of like how weights work for your muscles. This helps tone and strengthen the muscles you use to breathe.

    ❓Is there evidence it actually works?

    Absolutely. It’s built around Respiratory Muscle Training (RMT)—a method doctors, athletes, and therapists have been using for years to boost lung strength and breathing. Studies back it up: resistance breathing can expand lung capacity, cut down on that “out of breath” feeling, and even help folks bounce back from. Results depend on sticking with it, but lots of users notice better breathing, more stamina, and fewer cravings within a few weeks.

    ❓What’s a spirometer, and does this count?

    Yep, the NESLEMY™ LungFit Trainer doubles as a digital spirometer. It tracks exactly how much air you’re breathing in or out (in milliliters, mL), so you can see your lung capacity improve over time—no guessing.

    ❓Why even bother with RMT?

    Simple: The NESLEMY™ LungFit Trainer is all about helping you breathe easier and feel better, no drugs, no fuss. It strengthens your lungs, ups your stamina, eases stress, and supports recovery—whether you’re shaking a habit, bouncing back from an illness, or just dealing with breathing issues. It’s super easy to use, takes only a few minutes a day, and works for everyone: athletes, singers, or anyone who wants to breathe deeper and more comfortably. Small tool, big results.
