Breathing device to enhance and strengthens lungs
Stay ahead of the competition! Boost your endurance and stamina to increase your threshold and amplify your strength. The O2 Trainer reduces the effects of hypoxia and improves muscular growth so you are prepared to compete at any elevation. The device is compact, light and easy to use during intense training. The O2 Trainer was based on a simple, yet powerful concept. By controlling air intake, you immediately begin breathing the right way; using your diaphragm. The smaller the air intake hole, the harder your lungs need to work to pull air in, strengthening and condition the diaphragm muscles. Training regularly with the O2 Trainer will improve your blood circulation so that nutrients are transported to tissue more efficiently for better muscle nourishment and enhanced joint flexibility. Your body will not have to work as hard to pump blood leaving you with more energy, enhanced cardiovascular endurance and increased strength.
  • Greater Lung Strength
  • Enhanced Endurance

How It Works

Improve Breathing Power

The O2 trainer restricts air intake to strengthen your abdominal muscles and regulates your breathing form - training your body to properly take in deeper breaths and more oxygen.

Defeat Training Fatigue

The ability to intake more oxygen and breathe properly leads to improved body composition and supports a healthy circulatory system.

Gain Lean Muscle

Change resistance levels by using one of the 14 included air intake caps. As your endurance increases, change out the intake cap to reduce airflow and increase resistance. As your air intake decrease your body will build muscle strength while learning proper form for deeper breaths.
