  • Patent number: 4757993
    Abstract: Exercise devices with an adjustable handle and lever arm are provided for exercising the major muscle groups individually against a selected resistance. The exercise devices include a frame with a base and a leg, and a lever support is pivotably attached at one end and is adjustably attached to the leg at the selected distance from the lever support pivot. An exercise handle with a handle lever is connected to the lever support at a handle lever pivot and a resistance lever is also pivotably connected to the lever support. By adjusting the attachment of the lever support to the leg, the lever pivots are placed at the desired height from the base. The resistance lever is connected to a resistance source by a flexible connector which transmits the resistance from the resistance source in the general direction originating from the lever support pivot to the resistance lever.
