Abstract

An exercise machine includes a rocker pivotally attached to a base. Pins are attached to the bottom of the rocker. Pins are attached to the base. Tensioned elastic members each extend from a pin in the base to a pin attached to the bottom of the rocker. The elastic members assist or oppose each other depending on the position of the rocker. The elastic members function to rotate the rocker in different directions when the rocker is pivoted to different positions.

Claims

1. An exercise machine including

(a) a primary stationary support frame including

(i) a knee rest,

(ii) a first pin, and

(iii) a second pin,

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

(i) a chest rest generally normal to said knee rest,

(ii) a rotatable plate including a plurality of circumferentially placed apertures,

(iii) primary and secondary pins each removably insertable in each of said apertures,

said rocker movable between at least two operative positions,

(iv) a first upright operative position with said plate in a primary position, and

(v) a second operative position with said rocker canted from said first upright position and said plate rotated from said primary position;

(c) a first tensioned elastic band extending from said first pin to said primary pin;

(d) a second tensioned elastic band extending from said second pin to said secondary pin to oppose or assist said first band;

said primary and secondary pins having a first operative position in which moving said rocker from said first operative position to said second operative position

(e) increases the tension on said first elastic band, and

(f) decreases the tension on said second elastic band.

2. The exercise machine of claim 1 in which said primary and secondary pins have a second operative position in which moving said rocker from said first operative position to said second operative position

(a) decreases the tension on said first elastic band, and

(b) decreases the tension on said second elastic band.

3. The exercise machine of claim 1 in which said primary and secondary pins have a third operative position in which moving said rocker from said first operative position to said second operative position

(a) increases the tension on said first elastic band, and

(b) increases the tension on said second elastic band.

4. An exercise machine including

(a) a primary stationary support frame including

(i) a knee rest,

(ii) a first pin, and

(iii) a second pin,

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

(i) a chest rest generally normal to said knee rest,

(ii) a rotatable plate including a plurality of circumferentially placed apertures,

(iii) primary and secondary pins each removably insertable in each of said apertures,

said rocker movable between at least two operative positions,

(iv) a first upright operative position with said plate in a primary position, and

(v) a second operative position with said rocker canted from said first upright position and said plate rotated from said primary position;

(c) a first tensioned elastic band extending from said first pin to said primary pin;

(d) a second tensioned elastic band extending from said second pin to said secondary pin;

said primary and secondary pins having

(e) a first operative position in which moving said rocker from said first operative position to said second operative position

(i) increases the tension on said first elastic band, and

(ii) decreases the tension on said second elastic band;

(f) a second operative position in which moving said rocker from said first operative position to said second operative position

(i) decreases the tension on said first elastic band, and

(ii) decreases the tension on said second elastic band; and

,

(g) a third operative position in which moving said rocker from said first operative position to said second operative position

(i) increases the tension on said first elastic band, and

(ii) increases the tension on said second elastic band.
