Hey Maki

Thanks for your reply! I have just come back from half hour power plate session, it really does seem to work. I do pilates style exercies (I think, I have never done pilates), and the machine vibrates and contracts your muscles 35/50 (depending on setting) a second.. There are some trainers that say it is no good and does not work, and some trainers that think it is great and use it themselves. So far I am very happy, my stomach area is hard (well, underneath tha fat...). anyway, so far so good!
