ABSTRACT:
A device for weight training is attached to a weight lifting apparatus, such as a barbell or a selectorized weight machine, to provide a continuously variable resistance force to the lifting bar of the apparatus. As the power demands of the particular exercise decrease and then increase over an exercise cycle due to the musculoskeletal characteristics of the body, this device provides increasing and then decreasing resistance force to dampen out the variations in the power demands over the exercise cycle. A length of latex tubing intended for a specific exercise can be used to provide the variable resistance force. The latex tubing is connected at one end to the weight lifting apparatus and at the other end to an anchor, such as a platform loaded with weights.
