Portable lung capacity trainer, fitness running swimming abdominal breathing exercise device to help lung movement expand and restore lung capacity improving trainer - black

Help: Take out the resistive breathing trainer and rotate it left and right. Set the appropriate resistance strength. Check that the mouth nozzle is firmly fixed, and gently chew and close the mouth with your teeth to avoid air leakage. Inhale slowly through your nose until your lower abdomen is fully enlarged and your abdomen is slightly elevated. Apply pressure to your abdomen, then use a trainer to slowly exhale air through your mouth. In the initial phase, focus on adaptation. Each group consists of deep inspirations and exhalations. Start with 10-20 sets and work your way up to 30 sets, or if you can do it easily, gradually increase the resistance. Alternatively, training can be measured by duration, with 5-20 minutes of training per day depending on the individual's fitness.
