Right so my pesky asthma is getting better due to cranking up my inhaler usage, but I stumbled across this on twitterhttp://www.powerbreathe.com/powerbreathe-products/powerbreathe-classic-products/powerbreathe-classic-heavy-resistance-sports.html
powerbreathe lung muscles trainer, has anyone had any experience with one?... they seem good and at £30 worth a go, plus the vid says you just have to do 30 breaths 2x a day...seems like a simple and useful device for a feeble lunged weekling like me
any good?.... any feedback?...
