ABSTRACT:
An exercise machine for exercising the calf muscles of a seated exerciser includes: a frame configured to rest on an underlying surface; a seat assembly mounted on the frame on which the exerciser sits; a movement arm pivotally interconnected with the frame forwardly of the seat assembly; a heel pad mounted on the frame forwardly of the seat assembly and configured to receive the heel of the exerciser; a trailing link pivotally attached to the movement arm; a foot engagement member attached to the trailing link such that the foot engagement member is positioned above and forwardly of the heel pad, the foot engagement member having an engagement surface configured to receive a portion of the sole of the foot of the exerciser; and a resistance-imparting unit interconnected with the movement arm. The movement arm is movable by the exerciser between a flexed position, in which the sole of the foot of the exerciser engages the engagement surface of the foot engagement member as the heel of the exerciser engages the heel pad, such that the foot is generally perpendicular to the shin of exerciser, and an extended position, in which the foot points away from the shin as the sole of the foot of the exerciser remains engaged with the engagement surface of the foot engagement member and the heel remains engaged with the heel pad.
