1. A treadmill having a drive assembly;

  • the drive assembly having a front and a rear, the drive assembly comprised of;

    a parallelepiped block containing a drive motor, the block having two opposite ends;

    a rotatable belt, the belt having a front area, a midpoint, and a rear area, the belt further having an upper surface for user contact, the belt rotation perpendicular to the block;

    a drive roller in communication with the belt, the drive roller disposed at the front of the drive assembly;

    a drive motor incommunication with the roller;

    a rear roller in communication with the belt, the rear roller at the rear of the drive assembly;

    a spaced apart pair of vertical stanchions attached to the opposite ends of the block;

    a platform perpendicularly affixed to a bottom of each stanchion;

    a skid attached proximal to the rear of the drive assembly;

    a bottom of the skid equipped with a slideable material for sliding across surfaces;

    a housing affixed atop the stanchions;

    a CPU disposed within the housing, the CPU in communication with the drive motor;

    a control panel affixed to the housing, the control panel in communication with the CPU, the control panel comprising;

    means for programming a simulated course for walking and running;

    means for programming difficulty of the course;

    means for initially programming course speed;

    three speed detection sensors disposed below the belt upper surface, the detection sensors comprised of;

    an acceleration sensor disposed proximal to the front area of the belt;

    a target speed sensor disposed proximal to the midpoint of the belt;

    a deceleration sensor disposed proximal to the rear of the belt,whereby the speed of the belt is smoothly transitioned to regulate the user'"'"'s position toward the midpoint of the belt upper surface.
