Described herein is a device for tightening the abdominal muscles (e.g., rectus abdominus) at any time, including prior to eating. In more detail, for a duration prior to eating, the vibration device may be held forcefully against the abdomen to impart vibrations to the abdominal muscles. While the vibrations are being imparted, the abdominal muscles may also be contracted. The vibration device may include a base having a first surface and second surface, with the second surface facing the abdominal muscles, and a shaft movable relative to the base along an axis, with the shaft extending outwardly from the first surface. A motor may be configured to produce vibrations substantially along to the axis. The vibrations may be of sufficient magnitude to cause corresponding vibrations in the base and thus the abdominal muscles. A mechanism may be used to control the motor.
