Hi, I've got one at home, not an actual power plate which as other posters have said, are a lot more powerful, but a different make. To be honest I use the power plate in the gym more than I do my one at home, typical me - buying a new exercise gadget and then not using it!
The thing with a power plate / any vibration plate - is you don't just stand on it; you do exercises on it, stretches, lunges etc (I do push ups etc on it as well). I really should start using my home model again seeing as its sitting in the conservatory
