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.

Calf extension weight training machine

A rowing weight training machine includes: a frame; a seat assembly attached to the frame; a movement arm pivotally attached to the frame and movable along a generally longitudinal stroke path between a forward position and a rearward position; a resistance-imparting unit operatively connected with the movement arm to provide resistance to the movement arm as it moves from the forward position to the rearward position; a pair of handles to be grasped by an exerciser; and a pair of extension members, each of which is attached to a respective handle such that each handle is free to rotate about a longitudinal axis of the extension member. The extension members are attached to the movement arm (preferably via a universal ball joint) such that each extension member is free to at least partially rotate relative to the movement arm about vertical, longitudinal and transverse axes. Also, the extension members are of sufficient length and the extension members are attached to the movement arm so that the handles can be separated by a distance of at least 24 inches when the movement arm is in the rearward position. In this configuration, the exerciser has the option of performing the basic rowing motion with the hands in any orientation, and can pull the handles along multiple vertical planes to multiple positions in front of the chest and shoulders or outside the chest and shoulders.
