Abstract:
1. Apparatus for bi-directional torso exercise movements, comprising: a mainframe including a base and vertically extending columns at either side thereof; a seat mounted on the mainframe for supporting and positioning a user; a “U” shaped first sub-frame, disposed in a plane transverse to the mainframe and mounted to the mainframe, with a horizontal cross-bar located below the seat, so that the cross bar pivots parallelly about a horizontal first axis passing above the seat and proximate the abdomen of a seated user; a second sub-frame mounted to the first sub-frame cross bar for pivotal movement about a second axis, perpendicular to and intersecting the horizontal first axis, and having lever arms, for application of an input effort causing pivotal movement of the second sub-frame about the first axis; and a motion transfer linkage whereby pivotal movement of the second sub-frame about the first axis simultaneously forces its pivotal movement about the second axis.
