Ultrabreathe ASI7492 Compact Breathing Exerciser by Angel Sales

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 1-1/4 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

Owner Reviews, Ratings, Comments and Criticism
I'm no doctor, so I'm only writing this as someone with breathing problems. Inhaling is mostly a passive function. So when you use this device, the muscles involved in inhaling are coaxed into being active. I can feel them working differently than they usually do, and it's quite a workout! It's analogous to the benefit that a really bulked-up football player gets when he stretches. Most of the time he's contracting his muscles, but it's important that he lengthen them, too. In yoga, when you do any posture, you almost always follow up with a complementary position -- a counterposture. In both activities, maintaining flexibility doesn't only enhance your ability; it also helps prevent injury. When I use this device, I can feel muscles that I don't usually feel, and they're getting stronger. It increases my stamina and helps me prevent the symptoms that usually accompany strenuous activity. It works beautifully for me.
