A total body exercise machine in which an individual, seated in a body support sled, in a front or rear facing position, may use leveraged bodily force to elevate the sled against hydraulic and weighted resistance. A line trolley, suspended from a header by an assembly of pulleys and lines, tracks on a pair of rails, to pivotally support the upper end of the sled frame. At its lower end, the sled is pivotally joined to a frame mounted, radial indexing apparatus. That apparatus operatively positions a set of front and rear foot platforms, linked to the sled, to transmit leg force and assist in its elevation. Attached at the end of the lines is a set of hand rings, with which the user may use arm force, to help elevate the sled. Finally, the machine frame assembly is collapsible for shipping.

1. An aerobic sled exercise machine comprising:a frame having a pair of sleeves fitted to telescopically receive, in sliding fit, a pair of rails joined to an adjustable height header; an adjustable length bar prop, fixed at its upper end to said header, and disengagably attached at its lower end to the frame; a pair of transversely housed pulleys, axially joined to the header, and a pair of swivel pulleys, rotatably attached to the header; a centralized lift trolley that is slidably engaged to track on the rails; said trolley is suspended from the header pulleys by a pair of lines that are anchored to the movable trolley, and rigged, to traverse an assembly of trolley and header pulleys, to leverage a set of hand rings at their end points; a radial indexing apparatus having an index arm with an attached radial drum, and a bifurcated drum housing, each pivotally mounted, on a common drum axis of the base frame, with means to adjust the angular displacement of the drum housing relative to the drum index arm; a body sled frame pivotally suspended, at its upper end, to the lift trolley, and pivotally suspended at its lower end to the drum index arm; a foot platform attached to a first extension of the bifurcated index housing; a tow bar pivotally attached to a second extension of the bifurcated index housing; a leg lever, with an attached foot platform that is pivotally joined to the base frame and to the tow bar, to operatively transfer leg force from the lever, through the indexing assembly, to the sled frame; an adjustable, hydraulic cylinder pivotally connected to the index arm and to the body sled frame, to moderate resistance to sled frame elevation.
