FREE SHIPPING to the entire country if you buy more than one. New, never used. Improve resistance and physical performance: using a respiratory trainer can enhance the strength and endurance of respiratory muscles; respiratory muscle fatigue is a limiting factor in training; strengthening respiratory muscles can extend training limits and help you achieve better endurance. Adjustable resistance: the deep-breathing lung trainer is designed with adjustable resistance, allowing you to easily find and adjust the correct resistance level. You can set the resistance slightly lower at the initial stage and gradually increase it after becoming accustomed, enabling you to progressively develop improved lung capacity. High-quality material: the pulmonary breathing trainer is made of high-quality silicone material—non-toxic, odorless, harmless, and eco-friendly—so you can use it confidently. Lightweight and compact, it is portable. Usage recommendations: the lung capacity trainer adapts to all mouth shapes, fits perfectly, and is easy to use. Inhale slowly and deeply through your mouth and hold your breath for several seconds. Exhale slowly through your mouth until you are nearly out of breath. Then repeat the previous exercise 10 to 15 times to complete one set. Perform 2 to 4 sets per day. Wide application: pulmonary breathing trainers are widely used. You can use them for running, exercising, practicing yoga, playing ball games, engaging in sports, and other physical activities. They enable gradual improvement of lung capacity during exercise and help you achieve enhanced lung capacity more rapidly. Hand delivery available in the Odivelas area Or postal shipping nationwide
