An exercise apparatus includes a linear arm portion having an elongate arm member with proximal and distal ends and an elongate support member having proximal and distal ends. The arm member can be slidably mounted to the support member by a sliding joint positioned at the distal end of the support member. The arm member can be movable along a first axis between retracted and extended positions. The sliding joint can include first and second bearing assemblies which are spaced apart a sufficient distance from each other for constraining portions of the arm member within the sliding joint. The proximal end of the arm member that overlaps with the support member outside of the sliding joint when in retracted positions can be capable of some unconstrained lateral movement relative to the first axis. A linear arm brake assembly can be coupled to the arm member for resisting linear motion of the arm member. A torso portion can be included to which the linear arm portion is rotatably mounted about a second axis by rotary shoulder joint. The linear arm portion can be configured, and the rotary shoulder joint can be positioned along the length of the support member at a location that substantially balances the linear arm portion about the rotary shoulder joint at least when the arm member is in the retracted position.
