1. Apparatus for use in exercising a person's calves, which apparatus comprises a footrest, a kneerest, a length of stretchable material extending between the footrest and the kneerest, and fastener means for fastening the length of stretchable material, and the apparatus being such that:
(i) in use and with the person in a seated position then the front part of the person's feet rests on the footrest to retain the footrest on a floor, the kneerest rests on the person's knees, the length of stretchable material is stretched when the person pivots the rear part of their feet upwardly with respect to the footrest, the length of stretchable material contracts when the person pivots the rear part of their feet downwardly with respect to the footrest, and the stretching of the length of stretchable material requires effort from the person's calves which thereby exercises the person's calves; (ii) the fastener means fastens the length of stretchable material such that prior to use the length of stretchable material provides a fixed distance between the footrest and the kneerest, the fixed distance being that distance required by the person to provide the required effort during use of the apparatus when the person is pivoting the rear part of their feet upwardly with respect to the footrest; (iii) the fastener means comprises a clamp; (iv) the clamp is secured to the kneerest; and (v) the clamp comprises a clamping bar, a pair of guide rods on which the clamping bar slides, a handle, and a screw threaded shaft which is connected to the clamping bar and the handle such that rotation of the handle one way causes the clamping bar to clamp the length of stretchable material with respect to the kneerest, and rotation of the handle the opposite way causes the clamping bar to unclamp the length of stretchable material. |
