Hello all, pls has anyone used the power board fitness machine. It is an exercise machine that you stand on and it vibrates your whole body. I will like to know if it is ok to buy it and use for exercise since am unable to do much bcos my mobilty is getting worse. I have aversvula neurosis caused by steriod and i have had pomidronte infusion but i doesnt seem to help. I have used the power board fitness equipment in south africa in 2008 then i had not been diagnoised with lupus and in the 10days i spent in South africa i was so fit and muscles toned. I will like to know if it is ok to purchase it.
