Exercise apparatus has a base to which is pivoted one end of a rockable arm, the opposite end of which is coupled to one end of a force transmitting line by means of which the arm may be rocked from and to a rest position. Movement of the arm away from the rest position is yieldably opposed by elastic resistance members which react between the rockable arm and the base. An upright arm is removably supported by the base and is equipped with one or more line guides about which the force transmitting line may be reeved. In one embodiment the line guide automatically compensates for variations in the force which must be applied on the rockable arm to overcome variations in the resistance of the resistance members.

[ I claim:] [1.] Exercise apparatus comprising a base having an upper surface on which a person selectively may stand, kneel, or sit; an elongate rocker arm; means pivotally coupling said rocker arm to said base at a level corresponding substantially to that of said surface and for rocking movements

[ I claim:] [1.] Exercise apparatus comprising a base having an upper surface on which a person selectively may stand, kneel, or sit; an elongate rocker arm; means pivotally coupling said rocker arm to said base at a level corresponding substantially to that of said surface and for rocking movements of said rocker arm about a first axis adjacent said surface from and to an at rest position in which said rocker arm is substantially coplanar with and extends beyond said surface of said base; a flexible force transmitting line connected to said rocker arm adjacent its opposite end and being operable to effect rocking movements of said rocker arm about said first axis; and yieldable resistance means reacting between said base and said rocker arm for yieldably resisting rocking movements of said rocker arm about said first axis from said at rest position and for returning said rocker arm to said at rest position.
