<p>A physical fitness training apparatus consisting of a mainly upright module (1), a training arm (3A-G) which projects out from the main module and rotates about a horizontal axis (20), and which has grips or manipulation devices (3A-B) for use by the person exercising, a loading arrangement (9) and a flexible tie (7A-B) and associated pulleys (12A-D, 15, 16) for load and motion transfer between the training arm (3A-G) and the load arrangement (9). The invention is characterized by having a main arm (2) which projects out from the main module (1) and may be adjusted at angles about the horizontal axis (20) mentioned above; the main arm (2) has a first pair of pulleys (12A-B) located near and over/under each other at the outer, free and of the main arm (2), with the flexible tie (7A, X, Y) running from an attachement point (3F) on the training arm (3A-G) in the gap between the pulleys in the first pair of pulleys (12A-B). Furthermore, the main arm (2) has another pair of pulleys (12C-D) located near and over/under each other at the horizontal axis (20) described above, for guiding the flexible tie (7A) between the pulleys in the second pair of pulleys (12C-D), and by there being an adjustment arrangement (4) so devised as to permit fixing the main arm (2) at various angles.</p> |
