An ergometer (28) is employed on an exercise cycle (10) having a flywheel (20) rotated by pedals (16). A selectively tensionable endless belt (26) extends around the perimeter of flywheel (20) and a separate strap (160) is attached to the endless belt (26) to extend tangentially from the flywheel (20). The opposite end of strap (160) is connected to one end of an indicator plate (162) with the other end of the indicator plate attached to one end of an extension spring (164). The extension spring (164) imparts a tensile load on strap (160) equal to the opposing tensile load on the strap (160) imposed by the frictional force acting between endless belt (26) and the flywheel (20). This force level is sensed by the movement of the indicator plate (162) which coincides with the extension of spring (164), which plate movement corresponds to the workout level being achieved. The workout level in terms of calories per minute is displayed by indicia disposed on the upper side of the indicator plate (162) visible through a window (30) formed in the frame structure (40) of the exercise cycle (10).
