Abstract

An exercise machine (100) for exercising the rotary torso muscles of the human body, whereupon a user's body is supported in a generally supine position. The machine is comprised of a frame structure (101) with a rotable upper torso support (105) (including a head and back rest (121)), a rotatable lower torso support (103) (including a seat (119)) and feet stabilizing rollers (110), aligned longitudinally. The device further comprises a knee cushion (104) for rotating the lower torso support (103) and a peg (106) upon a weight support arm (127) for holding free weights that impart resistance against the rotation of the upper and lower torso supports (105, 103). Supplemental resistance to the rotation movement may be provided by a belt mechanism (180 of FIG. 4) including a belt (181) wrapped around a cam (151) connected to the axle (157) of the upper torso support (105) and up through the weight support arm upon which free weights are placed.

Description

BACKGROUND OF THE INVENTION

[0001] (1) Field of the Invention

[0002] The present invention generally relates to an exercise machine, and more particularly it relates to a dual rotation rotary torso exercise machine that simultaneously exercises both the upper and lower torso in a generally supine position.

[0003] (2) Description of Prior Art

[0004] Exercise equipment designed to specifically focus on or isolate the abdominal muscles is well known in the art. However, such equipment does not provide for simultaneous isolated exercising of the upper and lower abdominal muscles through movement of the both the upper and lower torso.

[0005] Examples of devices designed to target rotary torso muscles traditionally have an arrangement similar to that disclosed in U.S. Pat. No. 6,575,884 to Eazor; and U.S. Pat. No. 4,456,245 to Baldwin. Eazor '884 discloses an abdominal exercise machine that lifts both the upper and the lower torso up in the same direction, rather than rotating them in opposite dire...
