Patent ID: 7452311

Claim:
An exercise machine comprising: a frame; an articulated force lever having a first force arm and a second force arm; a first end of the second force arm pivotally connected to the frame at a first pivot connection for rotation about a first fulcrum; a second pivot connection connecting the second force arm to a first end of the first force arm; a second fulcrum on the frame; said second force arm rotatable about the first pivot connection to the second fulcrum; a handle section connected to the first end of the first force arm opposite the second pivot; a load connected to the first force arm between the first and second ends whereby movement of the handle section in a first direction rotates the first and second force arms about the first pivot against the resistance of the load, movement of the handle section in a second direction rotates the first force arm about the second pivot against the resistance of the load, and where the position where the load is connected to the first force arm is adjustable; a load linkage connected at a first end to a load, where said load linkage is connected at a second end to the first force arm, the position where the load linkage is connected to the first force arm is adjustable to vary the load, and the load linkage is a tension strap; a seat assembly including a seat bar pivotally connected to the frame; a seat connected to the seat bar; said load linkage connected to the seat bar whereby the load is provided at least partially by an exercising person occupying the seat; said first force arm is arcuate; a pulley installed on the frame between the first force arm and the seat bar; said tension strap extending from the first force arm and over the pulley to the seat bar; and said pulley located at approximately the center of the arc of the first force arm.
