Abstract

An exercise machine includes a rocker and a weight bearing frame pivotally interconnected with the rocker. The rocker and weight bearing frame are each pivotally mounted on a support frame or base. The weight bearing frame opposes movement of the rocker when the rocker moves in one direction and assists movement of the rocker when the rocker moves in another direction. The rocker can move from an upright orientation to a second orientation in which the rocker is canted below horizontal.

Claims

1. An exercise machine (70) including

(a) a primary stationary support frame;

(b) a rocker attached to said primary frame at a first pivot point and including

(i) a knee rest,

(ii) a chest rest generally normal to said knee rest

(iii) handles,

(iv) a first arm , and

(v) a counterbalance weight, said rocker movable between at least three operative positions,

(vi) a first upright operative position,

(vii) a second operative position with said rocker canted from said first upright position, and

(viii) a third operative position with said rocker canted from said first upright position to a position below horizontal;

(c) a foot rest; and

(d) a secondary weight bearing frame

(i) including a second arm,

(ii) including a third weight bearing arm that opposes movement of said rocker from said first to said second operative position, and assists movement of said rocker from said second to said first operative position,

(iii) including a fourth weight bearing arm that assists movement of said rocker from said first to said second operative position, and opposes movement of said rocker from said second to said first operative position, and

(iv) attached to said primary frame at a second pivot point spaced apart from said first pivot point, said first and second arms pivotally attached such that when said rocker pivots about said first pivot point and said first arm is displaced, said second arm and said secondary frame are simultaneously displaced.
