The present invention relates to a walk-behind exercise machine, wherein when a user moves a drive gear toward a front or rear side by performing an operation of pressing a foot on a tread set, one end of the link rotates about the drive rod as a center axis, The rotation bar connected to the other end of the tread set is limited in position by the influence of the second sagging groove of the tread set so that the link draws the tread set to operate in the up and down and forward and backward directions, When the tread set is moved in the anteroposterior direction by being pulled by the link, the first sagittal groove is provided with a space in which the tread set can move in the anteroposterior direction, and at this time, the shaft rod, the driving rod, Because the heights are the same, the users heel has moved to the bottom of the link along the back edge of the tread set The front end of the footrest is forcibly erected relatively and the stretching effect is further generated in the leg portion. Further, when the link pulls the driving rod and the driving gear to make the interlocking rotation, And simultaneously the weighted inertia wheels of the metal material disposed on both sides of the inertia wheels are rotated together. At the same time, the two inertia wheels rotate at the same time, accelerating action is generated, As a result, the user can drive and rotate the driving wheel set continuously in the same direction while using less force, so that the two sets of tread plates can be continuously lifted and lowered, and the operation of stepping on the foot plate can be made more smooth .본 고안은 보행식 운동기에 관한 것으로서, 사용자가 발판을 디딤판세트에 두고 밟는 동작을 하여 구동기어를 전방 혹은 후방을 향해 전동 시킬 때, 링크의 한 끝이 구동막대를 중심축으로 하여 회전하기 때문에 링크의 다른 한 끝에 연결된 회전봉이 디딤판세트의 제2용치홈의 영향을 받아 위치가 제한되고, 그로 인해 링크가 디딤판세트을 이끌어 상하 및 전후 방향으로 작동을 하게 되며, 또한 고정식 축막대의 외부테두리에서 회전할 수 있는 슬리브를 함께 사용하여 디딤판세트가 링크의 이끌림을 받아 전후 방향으로 이동할 때, 제1 용치홈은 디딤판세트가 전후방향으로 이동할 수 있는 공간을 제공하게 되고, 이때 축막대, 구동막대, 심축의 높이가 서로 동일하기 때문에 사용자의
