Fecha de publicación: 17/04/2019 Fuente: WIPO "bee" The present invention provides an exercise device which strengthens femoral muscle and gluteus while protecting knee and ankle joints by allowing a leg to move with a lower end of an arm placed on a thigh in a position where a user sits or lies, in order to minimize load or stress applied to the knee and ankle joints when performing exercise suitable for femoral muscle and gluteus exercise such as a leg press or a total hip, a fixed indoor bicycle, and an outdoor bicycle. To this end, the exercise device according to an embodiment of the present invention comprises: a sitting part on which a user can sit or lie; and an arm which is attached to a position of a hip joint of the user on a sagittal plane to be able to rotate, and has a structure which allows one end of the arm to be covered over a thigh of the user to be able to rotate. The exercise device according to an embodiment of the present invention has various resistance bodies for generating resistance against rotation of an arm part. Also, a device allowing a user to change a rotation shaft is provided. The exercise device according to another embodiment of the present invention includes two different rotation shafts on one arm. In addition, the exercise device according to an embodiment of the present invention has a form of a bicycle such that the rotation shaft of the arm is positioned on a hip joint part, and one end of the arm is covered over a back side of a thigh. Also, the exercise machine is rotated as the arm part (32) rotates in a clockwise direction and idles as the arm part rotates in a counterclockwise direction, thereby driving rear wheels to drive a bicycle.
