A calf exercise machine has a floor engaging main frame, a user support pivot, a user support assembly pivotally mounted on the main frame via the user support pivot, and a pivotally mounted user engagement device. A user engaging foot plate assembly is pivotally mounted to track movement of the user's feet during a calf exercise, and may comprise either the user support in a standing calf machine or the user engagement device in a seated calf machine. A connecting link translates movement of the user engagement device to movement of the user support so that pivotal movement in the user engagement device results in a self-aligning, pivoting movement of the user support.

The apparatus of claim 2, wherein the connecting linkage comprises at least one connecting link pivotally connected between the exercise arm assembly and the lifting arm, whereby the lifting arm is moved in response to movement of the exercise arm assembly during a calf exercise. 4. The apparatus of claim 3, wherein the lifting arm is pivotally connected to said at least one foot plate, whereby the foot plate is rotated in response to movement of the lifting arm. 5. The apparatus of claim 1, wherein the load is mounted on the lifting arm. 6. The apparatus of claim 5, wherein the lifting arm has at least one weight peg and the load comprises one or more weights mounted on said at least one weight peg. 7. The apparatus of claim 3, further comprising a pivot mount on the main frame which pivotally connects the lifting arm to the main frame. 8. The apparatus of claim 7, wherein the connecting link is linked to the lifting arm at a location spaced forward from the pivot mount. 9. The apparatus of claim 8, wherein said at least one foot plate is linked to the lifting arm at a location spaced rearward from the connecting link. 10. The apparatus of claim 9, wherein the lifting arm has a forward end and a rear end, and a drive link is pivotally connected between the rear end of the lifting arm and said at least one foot plate. 11. The apparatus of claim 8, wherein said at least one foot plate comprises two spaced foot plates which are connected together to move in unison during a calf exercise. 12. The apparatus of claim 1, wherein the exercise arm assembly has a forward end and a rear end, the main frame has a generally upright strut and the exercise arm assembly is pivotally connected to the upright strut at first location spaced between the ends of the exercise arm assembly, and the shoulder pads are mounted adjacent the forward end of the exercise arm assembly. 13. The apparatus of claim 12, further comprising at least one counterweight at the rear end of the exercise arm assembly. 14. The apparatus of claim 12, further comprising at least one lifting arm movably mounted relative to the main frame, the connecting linkage comprising a connecting link extending between the lifting arm and exercise arm assembly and pivotally linked to said at least one exercise arm at a second location spaced between said first location and said shoulder pads. 15. The apparatus of claim 14, wherein the connecting link has a lower end pivotally linked to the lifting arm. 16. The apparatus of claim 1, wherein the foot plate assembly is pivotally mounted on the main frame for rotation about a foot plate pivot axis, and said at least one foot plate is adapted to rotate between a forward inclined and a rearward inclined orientation during a calf exercise. 17. The apparatus of claim 16, wherein at least a major part of the at least one foot plate is located in front of a vertical gravitational center line extending through the foot plate pivot axis in a start position of a calf exercise and a major part of the at least one foot plate is located to the rear of the vertical gravitational center line at the end of a calf exercise. 18. The machine of claim 1, wherein the main frame has a floor engaging base portion and the foot plate assembly is pivotally mounted on the base portion of the main frame. 19. A calf exercise machine, comprising: a stationary main frame;a user support adapted to support a user in an exercise position and pivotally mounted relative to the main frame for rotation between a start position and an end position during a calf exercise;at least one user engagement device movably mounted relative to the main frame which is engaged by the user in performing exercises;one of the user support and user engagement device comprising a foot plate assembly adapted for engagement by a user's feet when performing a calf exercise and rotatable during a calf exercise to accommodate rotation of a user's feet about the ankle joints to contract the calf muscles;a connecting linkage which translates movement of the user engagement device to movement of the user support;at least one lifting arm movably mounted relative to the main frame and associated with at least one of the user support, user engagement device, and connecting linkage, whereby the lifting arm moves in response to movement of at least one of the user support, user engagement device, and connecting linkage; and a load which resists movement of the lifting arm. 20. The machine of claim 19, wherein the user support comprises the foot plate assembly and the user engagement device comprises an exercise arm assembly pivotally mounted on the main frame above the foot plate assembly. 21. The machine of claim 20, wherein the foot plate assembly has at least one pivotally mounted foot plate adapted to support a user in a standing position, and the exercise arm assembly has shoulder pads adapted for engagement by a user's shoulders when standing on said at least one foot plate. 22.
