Abstract
A weight training apparatus includes a track rotatably connected to a frame for rotation about a first axis to define a first moment arm. A weight is carried by the track at preselected positions for providing torque. A movement arm is pivotally connected to the frame to define a second moment arm. A coupling between the movement arm and the track causes a rotating of the track in response to a rotation of the movement arm. An angular movement of the second moment arm through a second arc length results in an angular movement of the first moment arm through a first arc length, wherein the second arc length is greater than the first arc length for all rotations of the movement arm and the track. The weight thus moves more slowly than the resistance arm.
Claims27
A weight training apparatus comprising:
- a frame;
- a track rotatably connected to the frame and pivotal about a first axis,
- a resistance block carried by the track at a relocatable preselected position along the track, wherein the resistance block and the track form a resistance block assembly having a center of gravity;
- a movement arm pivotal about a second axis, the movement arm having a user engagement portion for applying a force to the movement arm;
- a coupling connecting the movement arm to the resistance block assembly for rotating the track about the first axis in response to rotation of the movement arm about the second axis, wherein an angular movement of the center of gravity of the resistance block assembly through a first arc length results from an angular movement of the user engagement portion through a second arc length, and wherein the second arc length is greater than the first arc length for all rotations of the movement arm and the track, the center of gravity of the resistance block assembly thus moving more slowly than the user engagement portion.
A weight training apparatus comprising:
- a frame
- a track rotatably connected to the frame;
- a resistance block carried by the track at a preselected position thereon;
- a movement arm having a user engagement portion for applying a force thereto;
- and
- a coupling operably between the movement arm and the track for rotating the track in response to a movement of the movement arm, wherein a movement of the movement arm through a first length dimension results in an angular movement of the track through a second length dimension, and wherein the first length dimension is greater than the second length for all movements of the movement arm and the track, the resistance block thus moving more slowly than the movement arm.
