Abstract: An exercise machine wherein mechanisms are arranged to work selected muscle groups against an appropriate weight. More particularly, the exercise device includes a support frame, a shaft rotatably mounted to the support frame, a lever arm attached to the shaft for angular positioning thereof, an exercise lever arm, an incrementally adjustable weight system, a movable bench and an adjustably positioned exercise bar which exercise device allows an individual, when used in combination, to perform all of the conventional muscle group exercises required to maintain a fully-rounded fitness program.

Abstract: A physical training apparatus having at least one load member for engagement with and movement by an individual throughout a predetermined range of movement. A variable clutch device selectively applies torque from a motor to the load member. A load, having a magnitude which corresponds with the magnitude of torque applied to the load member, is applied to the individual by the load member. A sensor detects the position and direction of movement of the load member. A digital processor, connected to the sensor, controls the magnitude of torque applied to the load member by the clutch as a function of the location and direction of movement of the load member relative to the predetermined range of movement.
