ABSTRACT:
A resistance exercise apparatus employs a suspended weight as the primary source of resistance. A variable torque drive system is coupled to the suspended weight to selectively alter the amount of resistance experienced by the user. In one embodiment, the suspended weight is a single mass corresponding to the maximum resistance of the system. During the forward or "positive" stroke of an exercise, the drive system assists the user in lifting the mass, the amount of assistance being determined by a user selectable resistance value. During the return or "negative" stroke of the exercise, a reduced level of assistance may be provided so that increased negative resistance is experienced.
