XRT Pro 2.0 (10 Pack) Resistance Training Regulator Insert
Designed by Bas Rutten himself, the O2 Trainer is a lightweight and portable breathing exercise device for lungs that helps increase inspiratory (inhalation) muscle endurance. The breath trainer regulates air intake while also improving oxygen efficiency during exercise. With just 30 reps (under four minutes) of the O2 lung trainer, you will start to strengthen your inhale muscles which are your diaphragm and external intercostal muscles.
