Abstract
A weight training apparatus includes a telescoping pivot arm comprised of a concentric arrangement of an outer tube and an inner tube and configured to pivot about an axis and receive a weight at a predetermined position. The weight training apparatus further includes an actuator attached to the telescoping pivot arm and configured to cause relative motion between the inner tube and the outer tube to change a length between the predetermined position and the axis. The weight training apparatus further includes a sensor configured to output a signal indicative of an angular position of the telescoping pivot arm about the axis and a controller programmed to operate the actuator to cause the length to change based on the signal to achieve a target resistance profile.

A weight training apparatus comprising:
- a telescoping pivot arm comprised of a concentric arrangement of an outer tube and an inner tube and configured to pivot about an axis and receive a weight at a predetermined position;
- an actuator attached to the telescoping pivot arm and configured to cause relative motion between the inner tube and the outer tube to change a length between the predetermined position and the axis;
- a sensor configured to output a signal indicative of an angular position of the telescoping pivot arm about the axis;
- and
- a controller programmed to operate the actuator to cause the length to change based on the signal to achieve a target resistance profile.
A weight training system comprising:
- a telescoping pivot arm comprised of a concentric arrangement of an outer tube and an inner tube and configured to pivot about an axis and receive a weight at a predetermined position;
- an actuator attached to the telescoping pivot arm and configured to cause relative motion between the inner tube and the outer tube to change a length between the predetermined position and the axis;
- a sensor configured to output a signal indicative of an angular position of the telescoping pivot arm about the axis;
- and
- a controller programmed to operate the actuator to cause the length to change based on the signal to achieve a target resistance profile and, in response to a rate of change of the signal being indicative of the angular position changing at a rate less than a predetermined lift rate while the signal indicates rotation away from a rest position of the telescoping pivot arm and within a predetermined angular position range from the rest position, operate the actuator to reduce the length until the rate of change is greater than the predetermined lift rate.

- an actuator attached to the telescoping pivot arm and configured to cause relative motion between the inner tube and the outer tube to change a length between the predetermined position and the axis;
- a sensor configured to output a signal indicative of an angular position of the telescoping pivot arm about the axis;
- and
- a controller programmed to operate the actuator to cause the length to change based on the signal to achieve a target resistance profile, estimate the length based on a control signal provided to the actuator, and output, to a display, an average over a predetermined number of repetitions of a force value that is based on the length and the angular position derived from the signal.
