1. A computerized exercise machine comprising:

  • an exercise structure having a movable member for movement by a user to exercise on said exercise structure;

    resistance means associated with said movable member to resist the movement of said movable member;

    adjustment means mechanically associated with said resistance means for selectively varying the amount of resistance of said resistance means;

    resistance sensing means associated with said resistance means for sensing work performed by said user in moving said movable member against said resistance and including;

    a resistance responsive element connected to said resistance means, said resistance responsive element undergoing deformation in response to changes in the amount of resistance offered by said resistance means; and

    a piezoelectric element physically adapted to said resistance responsive element, said piezoelectric element being responsive to said deformation to translate said deformation to an electrical resistance signal;

    a motion sensor mounted to said exercise structure to sense the rate of movement of said movable member and to provide a movement rate signal reflective thereof;

    computer means associatively linked with said adjustment means for selectively controlling said adjustment means and communicatively linked to said resistance sensing means and said motion sensor to receive said resistance signal and said movement rate signal therefrom;

    pulse data input means connected between said user and said computer means for supplying pulse data to said computer means from said user exercising on said structure;

    input means connected to said computer means for receiving background data from said user and for selecting an exercise program and at least one exercise parameter related to said selected program; and

    display means mounted on said exercise structure and associatively linked with said computer means for displaying data computed by said computer means;

    wherein said computer means is operable to receive said selected exercise program including varying said amount of resistance of said resistance means selected by said user from said input means, to control said adjustment means in accordance with said selected exercise program and said varying amount of resistance over a preselected program duration, to read said pulse data from said pulse data input means, to read a user-selected target pulse rate from said input means, to compute said varying amount of resistance to cause said user'"'"'s pulse to approach said target pulse rate and in turn to control said adjustment means to change the resistances to said varying amount of resistance, to read said background data from said input means, to read the rate of movement of said movable member from said movement sensor,to read the resistances of said resistance means from said resistance sensing means, andto compute therefrom calorie use data.
