A treadmill having an adaptive speed control for the belt drive in which members engageable by the user to be pulled have signal generators associated therewith to enable signals proportioned to the degree of pulling to be used to correspondingly reduce a selected belt speed so that a lagging pace of the user is detected and the belt speed reduced automatically. Hand rails and/or pivoted vertical poles can be used as the user-engageable members. The mean position of the poles can be monitored to generate signals corresponding to the degree of pulling exerted by the user.
