ABSTRACT:
A machine for exercising leg muscles including a movement arm rotatable about a horizontal axis, a seat for receiving a user with the legs engageable with the movement arm to rotate it in one direction about the axis, and a weight stack including a resistance weight and a vertical stack pin connectable to the resistance weight. A sprocket is connected to the movement arm to rotate with the movement arm, and a drive connection including a chain or cable is established between the sprocket and the bottom of the stack pin to raise the stack pin when the movement arm is rotated in one direction. In one embodiment a drive lever is pivotally connected to the bottom of the stack pin to raise the stack pin when the movement arm is rotated in one direction in opposition to the resistance weight. The chain is connected to an intermediate portion of the drive lever. The movement arm is provided with a convenient handle for rotating the movement arm while the user is seated.
