After a friend of mine swearing blind about his success using a Powerbreath (www.powerbreathe.com), I went ahead and bought one today. It cost me an extortionate 60 pounds but if you are short on cash you can buy the old models which are apparently exactly the same in everything but appearance from Argos for 30 pounds. I have only used it once so far and its obviously too soon to see if it works yet but it certainly FEELS like its going to work. There is medical evidence supporting the manufacturers claims and the NHS apparently perscribes a mild version to asthmatics with good results so hopefully I havnt just flushed 60 quid away haha... Anyway just wondered if anyone had any experience using one. If so, how do you find it? For anyone thinking of getting one get either the red version or the black ironman one (both the same, just free DVD with ironman one and it looks cooler) as anyone approaching the fitness level required for the army will have no problems with this on its lowest setting. The highest setting however, wont even let me take one breath! J.
