Product Description Dual-Mode Breathing Exercise | With Bigbreathe IMT/PEP, you can perform both inhalation and exhalation exercises simultaneously. This device is equipped with an advanced pneumatic control device, allowing you to set the air resistance (air pressure) for both inhalation and exhalation. Inhalation increases the thickness of the diaphragm and lung capacity. Exhalation also helps to clear the airways and relieve shortness of breath. Adjustable Resistance | Setting the air pressure is also easy. Simply turn the IMT (Inhalation) or PEP (Exhalation) part left or right to change the resistance value. The red line inside the body will move up and down, and you can see the numbers. The larger the number, the greater the resistance. You can set the air pressure according to your physical strength and condition. You can gradually increase the difficulty to improve your breathing ability. Easy and Simple | To exercise, set the resistance level and completely cover the mouthpiece with your mouth. Inhale and exhale, each for 3-5 seconds. Once you start, do it for at least 5 minutes. No need to disassemble the parts to wash it after use! Just detach the mouthpiece and wash the mouthpiece and the main body with lukewarm water. Then, lay it on its side to dry. * Immediate purchase welcome, midnight silent purchase OK ◎ * One-of-a-kind, first-come, first-served * Welcome to bulk purchases, feel free to comment # Click here for Me-tan's product list ✨☜ ・Please understand and purchase for home storage and shipping in simple packaging (⁎ᵕᴗᵕ⁎) ・Please check the actual photos for the condition of the product ♪ ※ In order to sell as cheaply as possible, we may ship the product out of the box due to shipping costs.
