摘要：A multi-exercise system (10) is provided to actuate a resistive force loading responsive to an implied force by a user. A rotational actuation mechanism (84) is provided for bi-directional rotation about a singular axis (16) and coupled to an upper carriage (42) of resistive force mechanism (40). The rotational actuation mechanism (84) provides an initial rotative displacement in either of two opposite directions which is transformed into a linear displacement of the resistive force loading members (72). The rotational actuation mechanism (84) may include a sprocket wheel 86 whose rotative axis (16') is displaced from the sprocket wheel center (87') for compensating for the change in load force as the elastic cord members (72) are stretched.
