To this end, the present invention includes a sitting part on which a user can sit or lie, and an arm which is rotatably attached to a hip joint position of the user on a sagittal plane, wherein one end of the arm is formed to be rotatably hung on the thigh of the user. According to an aspect of the present invention, the exercise device includes a variety of resistors. Moreover, a user may change a rotation axis. According to another aspect of the present invention, two different rotation axes are provided for one arm. In addition, the exercise device is applied to a bicycle, wherein a rotation axis of an arm is disposed on a hip joint region, and one end of the arm is hung on the back of a thigh. The exercise device is rotated when being rotated clockwise according to the rotation of the arm (32), and is idled when being rotated counterclockwise. A back wheel is driven, and thus a bicycle is propelled. COPYRIGHT KIPO 2018
