How It Works
The Steel Lung Cardio Trainer works by adding resistance to your breathing, forcing your respiratory muscles to work harder with every inhale and exhale.
Just like lifting weights builds strength, this targeted resistance strengthens your diaphragm and lung capacity, improving oxygen intake and endurance over time.
By training your lungs to be more efficient, you’ll delay fatigue, recover faster between bursts of effort, and maintain peak performance when it matters most.
