A multi-function exercise machine includes a vibration machine which includes a base and a step seat. The base is provided with a driving device connected to a loading base which is able to swing and vibrate repeatedly. The top of the loading base is connected to the step seat while a rotating disc is arranged at the step seat. An adjustment part is pivotally disposed on each of two sides of the base and rotatable thereon. After being turned, the adjustment abuts against the base so that the loading base is fixed, unable to be wobbled. The rotating disc is pivotally disposed on the middle part of the step seat and able to be turned on the step seat.
