## Abstract

A portable exercise apparatus in the shape of a square having a handle at either side, which handles are arranged rotatable on spindles such that the user can impart movement on said apparatus without changing his/her grip.

## Claims

### Claim 1

An exercise apparatus comprising a rigid plastic frame comprising three first parallel struts, arranged orthogonally to two second struts, one at each end of said three first struts, all five struts being arranged in one and the same plane, whereby said two second struts connect said three first struts and wherein two outer struts of the three first struts each comprises a rigid spindle and an elastic sleeve, which sleeve rotates on said spindle, such that, when in use, said sleeves serve as hand holds by means of which the apparatus is to be held and manipulated.

### Claim 2 (depends on 1)

The exercise apparatus according to claim 1 wherein said rigid frame is molded in two halves from glass filled nylon or any material with similar properties.

### Claim 3 (depends on 2)

The exercise apparatus according to claim 2 wherein said two outer struts are molded as part of said two halves and, upon assembly of said apparatus, each half of said two outer struts meets its opposite half to form a spindle, each of which carries one of said rotating sleeves.

### Claim 4 (depends on 3)

The exercise apparatus according to claim 3 wherein a middle strut of the three first struts is formed in two halves which are, upon assembly, connected by a connecting screw which passes through said middle strut to engage with a threaded nut, thus holding the apparatus firmly together.

### Claim 5 (depends on 1)

The exercise apparatus according to claim 1 wherein said elastic sleeves are molded from a thermoplastic elastomer or any material of similar properties.

### Claim 6 (depends on 1)

The exercise apparatus according to claim 1 wherein said elastic sleeves have a profiled surface to ensure a secure grip for the user.

### Claim 7 (depends on 1)

The exercise apparatus according to claim 1 wherein said two second struts are hollow and comprise cut-outs in their front and rear walls for weight reduction purposes.

### Claim 8 (depends on 1)

The exercise apparatus according to claim 1 wherein said two second struts connect to the three first struts to form a square.
