The OXYFIT™ Breath Trainer uses adjustable resistance to strengthen your diaphragm and intercostals — 5 minutes a day, real progressive load, no app or subscription. KEY BENEFITS Stronger breathing muscles, better lung capacity Progressive resistance trains your diaphragm and intercostals like any other muscle. Less breathlessness under load The same effort feels easier — not because you are fitter, but because your breathing muscles do not fatigue as fast. More oxygen to working muscles Trained breathing muscles delay the metaboreflex — blood stays with your legs and heart when it matters most. 5 minutes. Daily. Done. Simple mechanical device, adjustable resistance levels, no app or subscription required. Best for: Endurance athletes, Combat sports, Biohackers — and anyone serious about training their breath.
