Patient's Perspective to this question:
I bought myself a vibrator plate to stand and get exercise as I have been deconditioned following my spinal injuries. This would give me the exercise of muscles to tone them and help take away muscle wasting.
My wife has used this religously as I told her it will slim her down but not drop her weight. Sure enough, she is firmer and slimmer after using it for 2 months. Her belly has gone in by 50% so far.
It appears that the loose muscles vibrate out air and tightening of muscles coming together for those who do not do active exercise. This vibrator works on entire body as it shakes you everywhere.
Do not overuse it if you want to try. Use only gradually on speed and stand in the centre mostly as slow speed can give too much vibration
to the spinal disc so what you cannot feel anything may cause other issues to do with disc degeneration. So use this to tone your muscles than trying an over night quick fix, but definately it will help make you slimmer everywhere.
