DETAILED DESCRIPTION OF THE INVENTION

(7) The fitness device includes a hollow body 14 of a cylindrical shape with an outer diameter of 186 mm, which is rounded towards the edges. In body 14 of the fitness device, handles 6 are placed horizontally against each other, projecting into the outer space (FIG. 1). Body 14 of the fitness device has two coaxial rings, inner ring 2 and outer ring 1, positioned in a reciprocally sliding relation, which includes outer sliding case and inner sliding case (FIG. 2). The body 14 has a minimum width of 100 mm. Width of body 14 is 137 mm, for example. On the inner surface of inner ring 2, a housing is mounted of handle-holding case 3, which extends longitudinally beyond the edges of body of the fitness device and has length of 178 mm (FIG. 3).

(8) Handles 6 are of a circular cross section and are mounted in housing by means of steel tube structure fitted along the longitudinal axis of hollow housing placed in tubular sleeve, equipped with safety pin of the tubular structure, which connects housing of the case 3 holding handles 6 with tubular sleeve. The two rings and are made of plastics; inner ring together with housing of the case holding handles constitute one casting. At the ends of housing, tubular sleeve is surrounded by spacing rings on the outer side. As best seen in FIGS. 1 and 3, the axis of handles 6 is off-set or lower than the rolling axis of the body 14. The axis of handles 6 is at a height of 63 mm, for example, from the mat, i.e. from outer surface of outer ring 1 at the place where the housing is connected with inner ring 2 (FIG. 3).

(9) Handles are bent upwards at the ends relative to the axis of handles at an external angle of 55; a length of the horizontal portions of handles up to the bend is 96 mm (FIG. 3). Handles are connected to housing of the case holding handles on tubular sleeve by a cotter by means of spring located on the outside of housing of the mounting of handles under spacing rings. (FIG. 2) By means of the cotter, handles can be easily detached from body of the fitness device and possibly slid into its interior space for easier transport and storage of the device.

(10) Outer surface of outer ring is provided with a textured surface of thermo-plasticized rubber (TPR). Handles are provided with a smooth rubber surface and the ends are equipped with plug.

(11) The shape of handles allows the grip of the device by the horizontal part or by the bent part and to alternate these two ways of gripping (FIG. 4a)-c)). This allows you to strengthen various muscles.

INDUSTRIAL APPLICABILITY

(12) The fitness device according to the invention serves to strengthen the abdominal muscles and related muscles. Placement of the axis of the handles under the longitudinal axis of the cylindrical body of the device as close as possible to the exercising mat and the design of the device rotation ensure smooth movement, stability of the handles, maximum and effective workouts and extended lifetime of the device. The shape of the handles makes it possible to strengthen various muscles, extends the number of exercise positions and improves the ergonomics of exercise. The device is easily portable and space-saving in terms of storage.
