Exercise machine

An exercise machine supporting a user in an inclined supine relation for performing a squatting exercise movement;

• said exercise machine comprising:
• a generally triangular support frame including a generally horizontal fixed base adapted to be supported on a supporting surface and a pair of opposed pivot supports at opposite ends of said base, a pair of upwardly extending diagonal frame members pivotally connected to said pivot supports and having upper ends pivotally connected to each other, one of said diagonal frame members being a body support frame member and the other of said diagonal frame members adapted to vary selectively the inclination of said body support frame member;
• a foot rest positioned adjacent the lower end of said body support frame member adapted to support the feet of a user and to restrain movement of the feet during the squatting exercise movement;
• a body support platform mounted on said body support frame member for reciprocating movement and having a shoulder restraint thereon adapted to contact the shoulder of a user in an inclined supine position on the platform whereby the user in a lower squatting position exerts force against said shoulder restraint and is restrained by said foot rest for moving said body support platform in an upward direction for straightening of the legs of the user, the user and platform moving in a downward direction by gravity upon bending of the knees and relaxing of the body while being restrained by said foot rest;
• and
• adjustable means to selectively vary the length of said other frame member for varying the inclination of said body support frame and body support platform thereby to vary the effective weight of the user when performing a squatting exercise.
