A sports training machine includes a frame having a first rotational axis and a second rotational axis, both ends of which are provided with a first linkage and a second linkage. The other end of the first linkage pivotally connects to a pedal bar. The other end of the second linkage pivotally connects to a pedal installed on the pedal bar in a sliding way. The first and second linkages rotate with respect to the first and second rotational axes, respectively. The user operates the pedals to perform independent reciprocal displacements upward and downward as well as forward and backward. |
