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.

Abstract: An exercise machine for performing leg curl and leg extension movements includes: a frame configured to rest on an underlying surface; an upper leg-supporting assembly pivotally interconnected with the frame, the upper leg-supporting assembly having a seat pad; a torso-supporting assembly pivotally interconnected with the frame and with the upper leg-supporting assembly, the torso-supporting assembly having a backrest pad; a leg curl assembly arm pivotally interconnected with the frame about a first pivot axis; a leg extension assembly arm pivotally interconnected with the frame about a second pivot axis; a resistance-imparting unit coupled with the leg curl movement arm and the leg extension movement arm; and a conversion mechanism interconnected with the frame and/or the torso-supporting assembly and the upper leg-supporting assembly.

Abstract: An exercise machine for exercising muscles in the back of an exerciser, includes: a frame; a seat assembly attached to the frame; a movement arm pivotally attached to the frame and movable along a stroke path between an upper forward position and a lower 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 the 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 such that each extension member is free to at least partially rotate relative to the movement arm about vertical, longitudinal and transverse axes.

Abstract: An exercise machine includes: a frame configured to rest on an underlying surface; a seat mounted to the frame; a backrest mounted to the frame above the seat, the seat and backrest being configured to receive a seated user; a pair of movement arm units pivotally interconnected with the frame and movable about respective generally parallel first and second axes of rotation; and a resistance system connected with the movement arm units. Each of the movement arms is configured to engage at least one of the elbows, forearms and hands of the user and is movable, within a range of motion plane that is generally normal to the first and second axes of rotation, between an extended position and a flexed position. The range of motion plane forms an angle of between about 30 and 80 degrees with the backrest.

Abstract: An inclined leg press machine includes: a frame that includes a base configured to rest on an underlying surface and a pair of inclined guides; a seat assembly attached to the frame; a weight sled slidably engaged with the guides along a travel path that is substantially parallel with the guides, the weight sled operatively coupled with a resistance source; and a foot platform assembly movable with the weight sled, the foot platform assembly having a foot platform that receives the feet of an exerciser. The weight sled is movable along the travel path between flexed and extended positions. The foot platform rotates relative to the underlying surface as the weight sled moves between the flexed and extended positions so that, when the exerciser's feet are placed flat on the foot platform, the exerciser's feet and tibiae are maintained at an angle of approximately ninety degrees.

Abstract: A leg press exercise machine comprises: a frame; a seat unit attached to the frame; a press mechanism attached to the frame, the press mechanism including a foot panel and at least one swing link pivotally interconnected with the frame; a resistance-imparting unit operatively connected with the press mechanism; and a resistance coupling mechanism attached to the press mechanism and the resistance-imparting unit. The press mechanism is configured such that the foot panel is movable along a generally longitudinal stroke path between a retracted position and a fully extended position. The resistance-imparting unit provides resistance to the foot panel as it moves from the retracted position to the fully extended position. The resistance coupling mechanism includes a drawing link pivotally interconnected with the swing link and a control link pivotally interconnected with the drawing link and the press mechanism. The control link is further attached to the resistance-imparting unit.

Abstract: An exercise machine includes: a frame resting on an underlying surface; a seat mounted to the frame and configured to receive a seated user; a pair of support pads mounted to the frame forwardly of and above the seat, each of the support pads positioned to engage one of the upper arms and the elbows of the seated user; a pair of movement arm units pivotally interconnected with the frame and movable about respective generally horizontal axes of rotation; and a resistance system connected with the movement arm units. Each of the pair of movement arm units is configured to engage the forearms and/or the hands of the user and is movable between an extended position, in which the seated user's arms are substantially straight, and a curled position, in which the user's arms are bent. The axes of rotation form an angle of between about 115 and 155 degrees.

Abstract: 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.
