IsoBreathe Lung Exerciser - Build Your Breathing
Just inhale through Isobreathe for a few minutes twice a day in a simple breathing pattern as shown in the instructions. Ultrabreathe 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. As your breathing power improves, Isobreathe can be gradually adjusted to provide more resistance with just the twist of a knob. Whether you're exercising for cardio fitness, or sports, you'll breathe deeper and more easily than ever. Within a month you will be on your way to feeling the wonderful effects of strong, healthy lungs!
