Whilst there are many underlying causes of breathlessness such as asthma, emphysema and bronchitis, clinical research shows that improving the strength and durability of the muscles we use to breathe in - muscles which may have lost strength over the years due to poor breathing habits or simply the ageing process - can both significantly reduce the sensation of breathlessness and lead to increased exercise tolerance and endurance. Unfortunately for many breathlessness sufferers the level of physical exercise required to exercise these muscles is not an option. Indeed many find themselves trapped in a vicious cycle of breathlessness and inactivity from which there seems no escape. Now, thanks to the Ultrabreathe, you can relieve the symptoms of breathlessness by giving your lungs a daily workout from the comfort of the armchair without the need for vigorous physical exercise. To begin with you set the resistance at a low level, gradually increasing it as your lung power improves. After a few weeks you should be starting to enjoy the benefits of Ultrabreathe training - and after a month or so just a few days training a week should be sufficient to maintain your enhanced lung function. In January 1999 a survey revealed that, of those who had used their Ultrabreathe for at least a month, 86% reported improvements in their 'breathing / physical condition.'
