HOW TO USE

1. Adjust the mask to fit securely – Use the strap system to lock it in place around your head.

2. Set your resistance level – Choose from multiple airflow levels to simulate different altitude intensities.

3. Train as usual – Shadowboxing, cardio, footwork, padwork — all while your lungs work harder.

  • This mask seriously changed my conditioning. After just two weeks of using it on level 3, I noticed a big difference in my endurance during sparring. Feels like I'm training at high altitude!

  • I was skeptical at first, but man… this thing works. The resistance makes breathing a challenge, which is exactly what I needed to push my cardio to the next level. Plus, it fits really well and doesn’t slip during movement.

    Jason L.

  • If you're serious about building lung power and mental toughness, get this mask. I’ve been using it on level 4 and already feel lighter and faster when training without it. Worth every dollar!

    BENEFITS

    The most powerful tool for building stamina and elite-level breathing control.

      Normal Breathing
    BOOSTED STAMINA
    CONTROLLED BREATHING
    CARDIO TOUGHNESS
    MENTAL DISCIPLINE

    SCIENCE BEHIND

    BOOSTED STAMINA

    Restricted airflow increases respiratory muscle activation — leading to stronger lungs and improved oxygen efficiency over time.

    CONTROLLED BREATHING

    By limiting oxygen intake, your body adapts to breathe slower and deeper, which enhances calm under pressure and recovery between exchanges.

    CARDIO TOUGHNESS

    Your heart and lungs are pushed harder, mimicking altitude training. The result? You’ll be able to push longer at high intensity.

    MENTAL DISCIPLINE

    Training under air restriction builds mental resilience — ideal for preparing for deep rounds or championship fights.

    Effect of Wearing the Elevation Training Mask on Aerobic Capacity, Lung Function, and Hematological Variables

    “Wearing the Elevation Training Mask (ETM) may improve specific markers of endurance performance beyond the improvements seen with interval training alone.”

    Eight Weeks of High-Intensity Interval Training Using Elevation Mask Improves Hematological Indicators and Pulmonary Function

    “8 weeks of mask training led to significant improvements in VO₂ peak, pulmonary function, and red blood cell count.”

    FAQ

    What’s the difference between THE O2 ELITE™ and THE O2 BASE™?

    THE O2 ELITE™ includes more difficult resistance levels and is designed as a full-coverage mask, which means you can naturally breathe through your noseduring training.

    THE O2 BASE™, on the other hand, offers fewer resistance levels and covers only the mouth area, making nasal breathing impossible.

    What does the mask actually do?

    It simulates training at altitude by restricting airflow, which strengthens your lungs and improves oxygen efficiency.

    Can I use it during sparring?

    We recommend using it only for drills, shadowboxing, or conditioning — not live sparring.

    Does it make a real difference?

    Yes — it mimics altitude-style training, helping to build endurance, cardio strength, and mental control.
