Bas Rutten O2 Trainer

The O2 Trainer is a small, portable breathing apparatus that controls air intake and enhances muscle oxygen use during exercise. Bas Rutten himself designed it to promote inspiratory (inhalation) muscle endurance. The O2 trainer does more than simply help athletes get better at their workouts. Your lungs and breathing muscles in your upper abdomen will get stronger after just under four minutes of exercise with 30 reps with O2. Your daily life will benefit from practicing your breathing!
