## Abstract

An exercise device includes a base part adapted to rest on a floor or another surface. The device includes a first upwardly extending part extending upwardly from the base part and, spaced apart upon the base part, a second upwardly extending part is provided. A lever frame, for supporting a person thereon, is pivoted by way of a pivotation mechanism relative to the first upwardly extending part. An engagement device is provided to act on the second upwardly extending part at a position higher than the lever frame so as to allow a person supported on the lever frame to engage with the engagement device to pivot the lever frame upwardly by way of the pivotation mechanism against the force of the person's weight acting on the lever frame and to thereby lift the person supported on the lever frame.

## Claims

### Claim 1

An exercise device, comprising;
a) a base part;
b) a first upwardly extending part extending upwardly from the base part;
c) a second upwardly extending part spaced from the first upwardly extending part and extending upwardly from the base part;
d) a lever frame for supporting a person thereon;
e) pivotation means for pivotally supporting the lever frame relative to the first upwardly extending part such that the lever frame is located substantially between the first and second upwardly extending parts; and
f) engagement means, associated with the second upwardly extending part, for acting on the second upwardly extending part at a position higher than the lever frame so as to permit a person supported on the lever frame to engage with the engagement means to pivot the lever frame upwardly by way of the pivotation means against the force of the person's weight acting on the lever frame and to thereby lift the person supported on the lever frame, the engagement means including a first link pivotally connected at one end to the second upwardly extending part and having a free end; a second link pivotally connected at one end to the lever frame remote from the pivotation means and pivotally connected at its opposite end to the first link between said one end of the first link and said free end of the first link; and a gripping means associated with said free end of the first link for allowing a person to grip said gripping means to exert an upwardly directed pulling force to cause pivoting of the first link and to thereby lift the second link, to pivot the lever frame about the pivotation means and to thus lift a person supported on the lever frame.

### Claim 2 (depends on 1)

A device as claimed in claim 1, in which the lever frame is adjustably supported by the pivotation means so as to vary the length of the lever.
