An exercise bench having a forward end and a rearward end comprising:
- a base frame;
- a bench mounted to the base frame;
- the bench including an elongate member having a seat mounted adjacent a rearward end thereof;
- a foot truck slidably mounted to the elongate member at a position spaced apart from the seat toward the forward end;
- a first pneumatic cylinder having an air inlet port and a piston;
- the first pneumatic cylinder attached to the base frame adjacent the seat and the piston connected to the foot truck whereby when the first pneumatic cylinder is pressurized the piston extends causing the foot truck to be slidably moved away from the seat;
- an upper body support pivotally mounted to an axle mounted to the base frame at a position above and behind the seat;
- the upper body support having a vertically upright member;
- a second pneumatic cylinder having an air inlet port and a piston;
- an arm fixedly secured to the upper body support with a free end extending in a direction perpendicular to the axle in a rearward direction;
- the second pneumatic cylinder attached to the base frame and the piston connected to the free end of the arm;
- whereby when the second pneumatic cylinder is pressurized the piston extends causing the arm and upper body support to pivot above the axle in a forward direction;
- a third pneumatic cylinder having an air inlet port and a piston;
- the third pneumatic cylinder attached to the base frame at a position above and behind the seat with the piston extending in a forward direction;
- a pelvic pad attached to the free end of the piston;
- whereby when the third pneumatic cylinder is pressurized the piston extends causing the pelvic pad to push against a user seated on the bench;
- a belt bracket slidably mounted to the upright member for movement in a vertical direction;
- a belt attached to the belt bracket for securing the user to the upper body support;
- a sliding member slidably attached to the upright member above the belt bracket for movement in the vertical direction;
- a fourth pneumatic cylinder having an air inlet port and a piston;
- the fourth pneumatic cylinder fixedly attached to the sliding member with the piston extending in a forward direction;
- a rest pad attached to the free end of the piston;
- whereby when the fourth pneumatic cylinder is pressurized the piston extends in the forward direction causing the rest pad to push against a user seated on the bench;
- a strap connected to the bench for wrapping over the knees of the user to secure the legs of the user to the bench;
- a strap connected to the base frame for securing the pelvic area of the user against the pelvic pad;
- a source of pressurized air fluidly connected to the inlet ports of the first, second, third and fourth pneumatic cylinders;
- and
- control means for adjustably controlling air pressure to each of the four pneumatic cylinders.
