An exercise device includes a frame, and upper and lower force receiving members movably mounted on the frame and constrained to pivot in opposite directions. A resistance device is preferably interconnected between the frame and at least one of the force receiving members to resist movement of the members toward one another and/or to bias the members away from one another. The lower member is configured to support a person's feet, and the upper member is configured to support a person's hands and/or to engage a person's chest. The device facilitates a combination crunch and leg lift exercise that involves both a person's upper abdominal muscles and a person's lower abdominal muscles. The device may be operated in a manner that facilitates exercise of a person's oblique muscles, as well.

What is claimed is: 1. An exercise apparatus, comprising: a frame configured to rest on a floor surface; a seat mounted on a first portion of the frame; an upper body support pivotally mounted on a discrete, second portion of the frame, wherein the upper body support and the frame cooperate to define a first pivot axis, and the upper body support is configured and arranged to extend generally vertically upward in front of the seat; a lower body support pivotally mounted on a discrete, third portion of the frame, wherein the lower body support and the frame cooperate to define a discrete, second pivot axis, and the lower body support is configured and arranged to extend generally horizontally outward beneath the upper body support and forward of the seat; and a constraining means, interconnected between the lower body support and the upper body support, for constraining the upper body support and the lower body support to pivot toward one another, and in respective, opposite directions relative to both the frame and the seat; and a resisting means, interconnected between the frame and the upper body support, for resisting downward movement of the upper body support relative to the frame; and wherein the second frame portion is disposed beneath a planform defined by the seat, and the third frame portion is disposed beneath the planform defined by the seat. 2. The exercise apparatus of claim 1, wherein the lower body support includes a bar that extends forward of the seat, and left and right lower foot members configured to support a person's feet, and left and right upper foot members configured to overlie the person's feet when resting on the lower foot members. 3. The exercise apparatus of claim 1, wherein the upper body support includes a first bar that extends upward in front of the seat, a second bar having opposite, distal ends that define respective left and right hand grips, and a universal joint interconnected between the first bar and the second bar. 4. The exercise apparatus of claim 1, wherein the seat is rigidly secured in place on the first portion of the frame. 5. The exercise apparatus of claim 1, further comprising a resisting means, interconnected between the frame and the upper body support, for resisting downward movement of the upper body support relative to the frame. 6. The exercise apparatus of claim 5, wherein the resisting means is interconnected between a portion of the upper body support that is disposed beneath a planform defined by the seat, and a portion of the frame that is disposed beneath the planform defined by the seat. 7. The exercise apparatus of claim 1, wherein the second frame portion is disposed beneath a planform defined by the seat, and the third frame portion is disposed beneath the planform defined by the seat. 8. The exercise apparatus of claim 1, wherein the upper body support is configured and arranged to be centered transversely relative to the seat, and to accommodate a person's legs on opposite sides thereof. 9. An exercise apparatus, comprising: a frame configured to rest on a floor surface; a seat mounted on a first portion of the frame; an upper body support pivotally mounted on a discrete, second portion of the frame, wherein the upper body support and the frame cooperate to define a first pivot axis, and the upper body support is configured and arranged to extend generally vertically upward in front of the seat; a lower body support pivotally mounted on a discrete, third portion of the frame, wherein the lower body support and the frame cooperate to define a discrete, second pivot axis, and the lower body support is configured and arranged to extend generally horizontally outward beneath the upper body support and forward of the seat; and a constraining means, interconnected between the lower body support and the upper body support, for constraining the upper body support and the lower body support to pivot toward one another, and in respective, opposite directions relative to both the frame and the seat, wherein the seat is rigidly secured in place on the first portion of the frame; and resisting means, interconnected between the frame and the upper body support, for resisting downward movement of the upper body support relative to the frame.
