A hand held device which almost anyone can use to exercise and strengthen their inspiratory muscles in the most effective way possible to relieve breathlessness. This device Powerbreathe has been modified and maufactured so that it is available for anyone to use and enjoy the benefits of better breathing. Powerbreathe uses a technique known as resistance training, in much the same way as you might use weights to increase the strength of your arm muscles. It has infact been called the (dumbells for the diagpragm) because it makes the breathing muscles work harder to improve their strength and endurance. Powerbreathe comes with a comforatble mouth piece and you simply breathe in through it, using a little extra effort of course, and the devise does the rest. Lab tests have shown that to get maximum benefit yuo only need to use Powerbreathe for 30 breaths twice a day. Within a few days your inspiratory muscles will feel stronger and within three weeks you'll be feeling less breathless. After only six weeks your inspiratory muscles should be in much better condition, so much so that you can maintain the benefits with only one Powerbreathe training session every other day.
