Exercising cart structure including a support beam, a front wheel frame and a rear wheel frame. One end of the support beam is connected with the front wheel frame, while the other end of the support beam is reciprocally slidably fitted with the rear wheel frame. Two front wheels and two rear wheels are respectively one-way rotatably mounted at two ends of the wheel shafts of the front and rear wheel frames. In use, a user sits on the seat and holds the handlebar of the front wheel frame with two hands with both feet stepping on two lateral step pads of the front wheel frame. The user's feet first push the front wheel frame forward by a certain distance and then the user's body and hip portion exert a force onto the rear wheel frame to move the same forward relative to the front wheel frame. Therefore, by means of forcing the front and rear wheel frames to alternately separate from and get close to each other, the exercising cart can gradually move forward. During the movement, a user can hold the handlebar to control the turning angle and moving direction of the exercising cart so as to achieve a harmonically and evenly exercising effect for the whole body.
Exercising cart structure comprising a support beam, a front wheel frame and a telescopic assembly having a rear wheel frame, one end of the support beam being connected with the front wheel frame, the other end of the support beam being nested into the telescopic assembly, a set of rollers being disposed in one end of the telescopic assembly facing the front wheel frame, the support beam being passed between and clamped by the rollers, a sliding end of the support beam being slidably fitted in the telescopic assembly, whereby the sliding end of the support beam is reciprocally telescopically slidable within the telescopic assembly, two front wheels and two rear wheels being respectively one-way rotatably mounted at two ends of the wheel shafts of the front and rear wheel frames, whereby by means of the reciprocal telescopic movement of the support beam relative to the telescopic assembly, the front and rear wheels alternately move forward to make the entire exercising cart move forward.
