Nafas lung trainer

This breathing trainer works by adding resistance to your breath, not by changing the oxygen level in the air. The oxygen concentration remains the same, what changes is the effort required to inhale and exhale. By creating controlled breathing resistance, the device strengthens essential respiratory muscles such as the diaphragm and intercostal muscles. With regular use, this leads to improved breathing efficiency and greater muscle endurance, particularly during physical activity. Stronger breathing muscles help your body perform better with less strain. As breathing becomes more efficient under exertion, the heart works more effectively, supporting overall endurance and cardiovascular performance.
