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.
The Ultrabreathe® device is patented, CE marked and manufactured in the UK to exacting European health & safety standards. With hundreds of thousands of users worldwide.
