Abstract: An exercising machine for use in simultaneously stressing muscle groups found in the limbs and trunk of a human user. The machine is characterized by a table having a bodysupporting surface including a body vibrator and an upstanding yoke adapted to receive the shoulders of a body in a supporting relationship; and a hoist for simultaneously stressing muscle groups found in the legs and trunk of a user's body, including a hand-driven windless mounted on the table substantially beneath the yoke in a position to be manipulated by the user as he is supported on the table in a face-down orientation, a sheave supported above the table, and a flexible line extended from the windless, trained about the sheave and adapted to be connected to the ankles of the user, whereby the user simultaneously lifts his trunk and legs above the plane of the back of his shoulders through a manipulation of the windless.
