An exercise device comprising (a) a frame, (b) first and second foot supports, (c) first and second connecting systems, each having at least two members pivotally attached to one another at a pivot point and interconnecting a respective foot support to the frame for moving the foot support along a closed loop path, (d) a means effective for sensing the speed of travel of the foot supports along the closed loop path, and (e) a means for automatically adjusting the stride length and/or stride height of the closed loop path traveled by the foot supports based upon the sensed speed of travel of the foot supports. The stride adjustment means includes (i) a means for adjusting the pivot point along the length of at least one member of the connecting system, and (ii) a control unit effective for receiving a signal from the sensor indicting the speed of travel of the foot supports along the closed loop path and automatically adjusting the pivot point along the length of at least one member of the connecting system based upon the received signal.
