A vibration apparatus and an associated motor assembly attached to a glove or wrap for a body part to stimulate muscle activity in the area of application. The apparatus is capable of generating vibrations of various amplitudes at the same frequency or within a defined frequency range. The device causes vibration in a limb to which it is attached, such that muscle that are not normally utilized in a single range of motion activity are activated. The mechanism creating the vibration may an eccentric rotating mass vibration motor assembly attached to a glove or wrist support. Use of the device with fitness equipment provides an individual with the benefits associated with vibrational motion such as increased muscle use with a single exercise motion and increased muscle memory during use with sports activities.
