In response to "I dont know about the power plate...but doing anything on top of an upside down Bosu trainer is legit -- nm" by Stewie

Agreed, and it's sort of the same concept, but more gimmicky.

The bosu ball or swiss ball stuff forces you to use your core more and use other stabilizer muscles. The argument is that the rapid vibration does the same. I just think it's less clear.
