For those of you looking for a whole body vibration machine, here is a simple and yet most effective tip: there is no single machine that will suit everyone equally well. Whole body vibration machines are made to meet the requirements of different kinds. Some machines are suitable for heavy exercise takers, while others are good for those who take light or moderate exercises. Some machines are meant to work well for body-builders, while others are suitable for those who want to maintain their health or get rid of basic issues like joint pains and body toxins.
And then, there are EMF and motor issues. Some machines produce a loud humming noise because of high EMF production, but quite often they tend to have high capacity. And from yet another point of view, there are machines that vibrate well in spite of heavy loads and there are other machines that do not. In summary, there are a number of options to choose your vibration machine from.
Depending upon your current health conditions and long term objectives, you need to choose whole body vibration machines that will suit your needs well. Make a careful choice and you will be able to really enjoy your vibration machine for a long time to come.
