Introducing the Ultrabreathe - the world's no. 1 selling respiratory trainer.Whether you're into sports and looking to supercharge your breathing muscles or maybe you suffer from a medical condition such as asthma, the Ultrabreathe can help you boost your breathing power. The Ultrabreathe is a highly effective inspiratory muscle trainer, providing an easy and convenient means of increasing the strength and durability of the respiratory muscles. It works on the principle of resistance. As you inhale, the resistance created makes your respiratory muscles work harder and the harder they work, the stronger and more durable they become - and as your breathing power improves, the Ultrabreathe can be gradually adjusted to provide more resistance. Ultrabreathe is used by athletes, sports people, singers and musicians the world over to supercharge their inspiratory muscles. Warm up: Supplement your usual routine prior to full body workout or competition - traditional techniques tend to ignore the breathing muscles.Performance: Follow our training regime for just 5 minutes per day to boost pulmonary capacity and endurance. Increase the resistance as lung function improves - and take advantage of the patented adjustable valve system which lets you select the moment resistance is experienced on inhalation.
