GO² Device for Endurance
Regular price $59.95
The GO² Device is the only breathing device scientifically proven to increase oxygen and endurance while lowering your heartrate. The device works by applying a slight pressure on the exhale, also known as Positive End Expiratory Pressure or PEEP, a physiological technique used in healthcare for 60+ years to increase oxygen in patients. The inhale is completely natural and can be done nasally or orally.
GO² benefits are rooted in proven science by independent third-party Ph.D. researchers from Texas A&M University and Houston Methodist Hospital and proven with statistical significance. This research showed an increase in VO2 Max by 4.1% and Endurance by 5.8%. You can view the research published in the esteemed Sports Medicine and Health Science Journal HERE
To quantify these numbers, using GO² will take 10 minutes off a 4-hour marathon time (5-6 mins off a 3-hour marathon).
Designed by Doctors for use in endurance sports such as running, cycling, hiking/climbing, CrossFit, Skiing and more. Made in the USA. Go Further, Faster with GO².
