On the left and right sides of the frame body 10, a catching portion 153 is formed on the top end portion, so that the user can grasp the grasping portion 153 to maintain the body during use of the fitness equipment. Balanced, and the swinging lever 151 is pivotally connected to the frame at a central position between the bottom end and the top end, and one of the left and right interlocking + dry 152 ends is pivotally connected to the bottom end of the two rocking bars 151, and the other end corresponds to each other. It is pivotally connected to the left and right swing arms 14. Therefore, when the pedal 13 is forced to start to act, the bottom end of each swing lever 151 swings back and forth as the swing arm 14 moves, so the pedal 13 also moves forward or backward along with the movement of the swing arm 14 . At this time, the top grip portion 153 of each swing lever 151 is reversely actuated with the corresponding pedal 13, so that during the operation, the user can train the lower body muscles by lateral movement of the pedal 13 during operation. Can be used with hand movements to achieve systemic coordination training. In summary, the structure of the leg reciprocating device of the present invention can provide a user to perform a reciprocating alternate action of the side legs of the skating, so that the user can satisfy the full training of the lower body muscle during the operation. The purpose is to increase the intensity of exercise. It is not only trained to the front and rear muscles. The lower half of the curve sculpture can be more perfect. Moreover, the skating action can train the user's body coordination, so that the user can strengthen the training body. The sense of balance and the coordination of the whole body and the obstruction of the flat pedal movement can reduce the user's discomfort in use and further reduce the occurrence of sports injuries.
