**Long term effects: After regular training (usually for several weeks), respiratory muscle strength and endurance can be significantly enhanced, manifested as increased lung capacity, increased maximum ventilation, improved respiratory efficiency (more oxygen can be obtained/more exhaust gas can be discharged per breath), reduced difficulty in breathing during daily activities or exercise, and easier and more effortless breathing. Function: Enhance Respiratory Muscle Endurance And Strength, Delay Respiratory Fatigue Caused By Exercise, And Improve Aerobic Exercise Performance. Improve Respiratory Distress Symptoms, Enhance Respiratory Efficiency, Improve Activity Endurance And Quality Of Life. As A Daily Respiratory Health Care, Improving Breathing Patterns, Relieving Stress, And Enhancing Overall Respiratory Function. Suitable For: Fitness Enthusiasts, Athletes, Singers, Wind Musicians, And Those Who Require Abdominal Breathing Training **Short Term Effect: * * After A Single Training Session, There May Be A Feeling Of Increased Breathing And Slight Fatigue In The Respiratory Muscles (Similar To Muscle Soreness After Exercise). **Core Functional Principle: Its Core Function Is To Provide Controllable And Progressive Respiratory Resistance. Users Must Overcome Preset Resistance When Taking Deep Breaths Or Exhaling Through The Device. This Process Of Resisting Resistance Is Like Lifting Dumbbells To Exercise Arm Muscles, Specifically Designed To * * Exercise And Strengthen Respiratory Muscle Groups** Training Method: Progressive Adjustable Weight 20g Breathing Training (10 Seconds Stable Breathing/Inhalation 10 Times 3 Groups) 69g Burst Training (30 Seconds Rapid Breathing/Inhalation 30 Times/3-5 Groups) 100g Combustion Training (30 Times/3-5 Groups) Gravity Free Adjustment Exercise Is More Effective
