ABSTRACT:
An exercise machine has a stand, a linking assembly, an elastic member, a seat, two handles, two pedals and two wheels. The linking assembly is mounted pivotally on the stand. The elastic member is connected to the stand and the linking assembly. The seat is mounted on the stand. The handles, the pedals and the wheels are attached to the linking assembly. The handles are operated against the elastic members and the linking assembly moves to drive an exerciser's legs to stretch out. Therefore, the exercise machine provides the exerciser to train the muscles of the arms and the legs synchronously.
