An exercise apparatus with a control mechanism is disclosed. The control mechanism is linked to a bank of horizontally arranged slide potentiometers, which act as user-movable indicators. The user can move these indicators up and down to indicate an ordered set of relative difficulty values. The exercise apparatus, such as a treadmill, is provided with a control mechanism to control the difficulty of the exercise engaged by the user on the exercise apparatus in relative difficulties corresponding to the ordered set of relative values selected. The exercise apparatus is adapted to engage in this ordered set during a chronological set of program steps.
