Abstract: A pace-adjusting mechanism of an elliptical cross trainer having an electric adjusting mechanism installed at the bottom of a front side of the frame unit. The electric adjusting mechanism includes a motor, a guide spindle sleeve, a telescopic spindle, a slide bar, a U-frame and two connecting rods. Both connecting rods are pivotally coupled to the front end of the treadle plank. The U-frame is pivotally mounted on the frame unit. When the guide spindle sleeve is driven by the motor to create a reciprocating in-place displacement of the telescopic spindle, it results in a change of the connecting angle between the slide bar and the U-frame. In this way, the U-frame changes its supporting angle. Then, the vertical position of the treadle plank and the treadle thereon can be adjusted by the coupling relationship of the connecting rods. Accordingly, the change of the exercise pace can be achieved.

Abstract: The invention relates to a structure of rocker arms with optical sensing control for an exercise apparatus. The rocker arm of an exercise apparatus includes a handgrip.
