The invention refers to a fitness device in the form of a garment for shaping the figure of a human body, said device comprising a sleeve which encloses the body at least partially in an airtight manner. A fitness device of this type is for instance known as a sweating suit. The sweating suit generates a sauna climate in its interior, which leads to an increased metabolism. Thus, the training results and the figure shaping may be improved. However, it is necessary for conventional sweating suits to wear these suits regularly over a longer period of time. Thus, the object of the invention is to provide a fitness device, which at least compared to the conventional sweating suits enables faster results in the figure shaping and which can be used in an aimed manner at certain parts of the body. According to the invention, this problem for a fitness device (1) of the above-mentioned kind is solved in that the sleeve forms a low pressure chamber (5) with at least one section of the body surface, said low pressure chamber being loaded with an air pressure that is lower compared to the atmosphere. The blood circulation is stimulated by the low pressure in the area of the low pressure chamber (5) and the metabolism in the fat-containing skin layers is increased. This leads to a faster reduction of fat. The fitness device may moreover be worn while simultaneously performing a regular workout training.
