Abstract
Abstract An exercise apparatus for more specific full range muscle development. The apparatus includes at least one weight, a guide for the weight and a pulley affixed to the weight. A line is reeved through the pulley and one end of the line terminates in a handle by which the line can be grasped by a person utilizing the exercise device. The other end of the line is anchored. The weight is free to move on the guide when a force is applied to the handle. Since the pulley is affixed to the weight, the weight moves as the exercise device is utilized and the direction of application of force constantly changes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
An exercise apparatus for specific muscle development comprising at least one weight, guide means for said at least one weight during movement of said at least one weight, pulley means for offering a resistance during exercising, said pulley means affixed to said at least one weight, and a line reeved around said pulley means, one end of said line terminating in a grasping means, said grasping means being grasped by a user to operate on the line and said at least one weight and the other end of said line being affixed to anchor means which secures the other end of the line during an exercise, said at least one weight and said pulley being free to move on the guide means when a user's force is applied to said grasping means, said grasping means and said pulley means on said weight being directly connected by said line without passing said line through any intervening pulley means whereby the direction of application of a user's force with respect to the pulley means constantly changes during use.
Claim 2
Dependent Claim
176 words
An exercise apparatus for specific muscle development comprising at least one weight, guide means for said at least one weight during movement of said at least one weight, pulley means for offering a resistance during exercising, said pulley means affixed to said at least one weight, and a line reeved around said pulley means, one end of said line terminating in a grasping means, said grasping means being grasped by a user to operate on the line and said at least one weight and the other end of said line being affixed to anchor means which secures the other end of the line during an exercise, said at least one weight and said pulley being free to move on the guide means when a user's force is applied to said grasping means, said grasping means and said pulley means on said weight being directly connected by said line without passing said line through any intervening pulley means whereby the direction of application of a user's force with respect to the pulley means constantly changes during use.
