I am an elite time trial cyclist and I have been using Power Breathe for 5 weeks and I would say what a brilliant device-it really does work. Jason (user)

My research over the past decade has convinced me that the work associated with breathing limits athletic performance. Athletes who want to maximise their performance should address their breathing specifically, because their normal training fails to do so. Our research shows that training with Power Breathe increases the power and endurance of breathing and improves athletic performance significantly. Dr Alison McConnell
