Abstract: An exercise apparatus especially suitable for simulating mogul skiing conditions. The apparatus may comprise a base which supports a rotatable component which, in turn, supports a platform for supporting a user. The rotational component includes a unidirectional element limiting the direction of rotation of the rotational component to a single direction. A biasing assembly assists and resists the movement of the rotational component and varies the speed of the rotational component in response to a displacement of the rotational component. An alternative exercise apparatus includes a pair of spaced rotational components driven by a prime mover via a power transmitting element. A platform is operatively connected to the pair of rotational components via a platform support assembly. One rotational element leads the other rotational element so as to vary the angular disposition of the platform throughout the rotation of the rotational elements. The prime mover is preferably a variable speed motor.
Abstract: A rowing exercise machine comprises a base, a first swinging member, a second swinging member, a seat tube, a seat, a third swinging member, a first pulley, a second pulley, a pull cable, a hand grip, and two pedals. A rowing exercise is brought about by a person sitting on the seat of the rowing exercise machine, with the person's feet pedaling the pedals and the person's hands holding the hand grip to pull rearwards the pull cable to cause the first swinging member and the third swinging member to move closer so as to actuate the seat tube to move upwards and rearwards. As the pull cable is relieved of the pressure exerting thereon, the seat tube is caused by the person's weight to move forwards and downwards so as to actuate the first swinging member and the third swinging member to move away from each other in opposite directions.
