Weight lifting simulator apparatus (1 ) includes a primary pneumatic cylinder (14) providing the principal resistance for simulating weight lifting exercise with at least one secondary cylinder (30) in free fluid interconnection with the primary cylinder (14) whereby constant and balanced loading is achieved, with provisions for dynamic simulation of weight inertia effect, and control thereof, as in lifting a real weight. The primary (14) and the secondary (30) cylinders are associated with a guideway (4), the primary cylinder (14) being fixed to the guideway (4) and the secondary cylinder (30) being slidable relative to the guideway (4) and pivotable relative to the piston rod (18) of the primary cylinder (14). Variation of the securement position of the primary cylinder (14) on the guideway (4) is available and valving (42) is provided in the fluid interconnection. |
