Abstract
Disclosed is a self-rotational exerciser including a fixed stand and a rotational frame freely rotatably connected to the fixed stand via two pivots. The rotational frame includes two elongated side posts, a seat lever connected to lower ends of the side posts, and a foot confining device downward extending from the seat lever for confining a user's feet thereto. A handle lever is connected between upper portions of the side posts for the user to grip. A stand-up position of the user on the rotational frame gives the rotational frame a center of gravity higher than the two pivots and therefore allows the rotational frame to rotate whenever the user tilts his/her body forward or backward. A sitting position or other positions of the user on the rotational frame that give the latter a center of gravity lower than the two pivots shall allow the rotational frame to stay in still either in a normal postion, an upside-down position, or an angularly inclined position. Without any help from an outcoming force, the rotational frame of the exerciser can be freely rotated or kept in still in any direction at different rotational speed just by the user's different body positions and movements of different parts of the body.
