Review on 🏃 GO2 Endurance Workout Device: Enhance Breathing & Oxygen Flow During Running, Cycling, and High-Altitude Activities - Made in USA by Zach Flores

I have used this in many different workouts when doing triathlons. Used in indoor cycling, running (short and long), and bodyweight circuits. From the very first breath you are immediately (hyper) aware of the breathing pattern, frequency and strength. Begins to adjust his thinking to focus on breathing and to be able to let the rest of the workout take care of itself. Only a few training units are required to use the device more and more comfortably. I will say that salivation has definitely increased, but as use increases you learn to control it more and more. Follow similar routes, efforts, etc. to see physiological changes for long-term benefit. Glad to see progress as the journey continues.
