A dumbbell consisting of a heavy core (1) around which there is an impact absorbing layer (2) capable of being shaped covered with a splinter-proof layer (3) on which a number of straps or bands (4) is provided. The impact absorbing layer and the splinter-proof cover that the dumbbells can hit against each other. The dumbbells are also protected by the two layers in case they are dropped-just as the risk of causing bodily injuries if the dumbbell falls down is reduced. Straps or bands on the dumbbell serving the purpose of fastening it to the hand moreover means that the risk of dropping the dumbbell is reduced. The straps/bands furthermore makes it possible to perform faster and longer movements of body and limbs in order to strengthen muscles and circulation without dropping the dumbbells. The construction with the major part of the weight of the dumbbell resting in the hollow of the hand reduces the wear on several of the sinews of the hand by varying courses of movement. |
