PRODUCT DESCRIPTION Do you ever feel a shortness of breath from simply walking up a flight of stairs Would you like to gain better lung stamina during vigorous workouts 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. Just inhale through Ultrabreathe 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 Ultrabreathe can be gradually adjusted to provide more resistance with just the twist of a knob. It can even help reduce the feeling of breathlessness from some lung diseases such as asthma bronchitis and emphysema. Doctors have been prescribing big bulky breathing devices for post-surgery patients to increase their lung power for years. Ultrabreathe gives you the same effects but is so small and compact you can take it with you to exercise your lungs wherever you are. Whether youre exercising for cardio fitness sports or not at all youll 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 Athletes who want to boost their performance and folks who suffer from breathlessness can all benefit from using this ingenious breathing exerciser. Heres how it works: after positioning the soft mouthpiece between the teeth and gums and biting down to create an airtight seal the user breathes in sharply and continues to breathe in hard for as long as possible. Then the breath is slowly exhaled. When repeated 25 times twice daily for at least a month the exercises should noticeably increase breathing strength. As improvement occurs the user can increase resistance by simply turning one or both parts of the device: the end cap (which holds a lightweight ball) and the valve sleeve. Measuring 5 by 2 by 1-14 inches the Ultrabreathe is so compact it will fit in a pocket or travel kit for use at work in bed or on the road. --Ann Bieri
