<p>A physical training apparatus (10) has a main frame (11), a moveable carriage (12) connected to the main frame (11), and an arm assembly (14, 15) having an end connected to the moveable carriage (12), and another end connected to a weight (13). The weight (13) is pivotally connected to a fixed pivot point (50). In use, a force exerted by a user on the carriage (12) causes the weight (13) to rise about the pivot point (5O), the force being transmitted through the arm assembly (14, 15), and whereby continued rising of the weight (13) requires a variation in the force to at least compensate for a variation in the resistance to movement of the weight (13) as it rises about the pivot point (50).</p> |
