Exercise resistance methods and apparatus
First Claim
Patent Images
1. A method of adjusting resistance to exercise, comprising the steps of:
 positioning a plurality of weights in respective rest positions;
moving a member into and out of alignment with the weights;
moving a weight selector on the member along a linear path, including a first portion of the path that extends over an upwardly unbounded portion of each weight in a first subset of the weights, thereby leaving the weight selector free to move upward relative to the first subset, and a second portion of the path that extends beneath at least a portion of each weight in a discrete, second subset of the weights, to selectively secure the second subset to the member for upward movement together with the weight selector.

Abstract
Weights are disposed on opposite sides of a base member, and selector rods are selectively moved into engagement with the desired number of weights on each side of the base member.

5. An adjustable weight exercise device, comprising:

a plurality of weights disposed in respective aligned positions; and a member sized and configured for movement into and out of alignment with the weights, wherein a weight selector is movably mounted on the member for movement along a linear path that extends over an upwardly exposed sidewall of each weight in a first subset of the weights, thereby leaving the weight selector free to move upward relative to the first subset, and beneath at least a portion of each weight in a discrete, second subset of the weights, thereby constraining the second subset to move upward together with the weight selector.

9. A method of adjusting resistance to exercise, comprising the steps of:

positioning a plurality of weights in respective rest positions; moving a member into and out of alignment with the weights; moving a first weight selector on the member linearly over an upwardly unobstructed sidewall of each weight in a first subset of the weights, leaving the first weight selector free to move upward relative to the first subset, and beneath at least a portion of each weight in a discrete, second subset of the weights to selectively secure the second subset to the member for upward movement together with the first weight selector; and moving a second weight selector on the member linearly over an upwardly unobstructed sidewall of each said weight in the second subset of the weights, leaving the second weight selector free to move upward relative to the second subset, and beneath at least a portion of each said weight in the first subset of the weights to selectively secure the first subset to the member for upward movement together with the second weight selector.


10. An adjustable weight exercise device, comprising:

a plurality of weights disposed in respective aligned positions; and a member sized and configured for movement into and out of alignment with the weights, wherein a first weight selector is movably mounted on the member for linear movement over an upwardly open sidewall of each weight in a first subset of the weights, leaving the first weight selector free to move upward relative to the first subset, and beneath at least a portion of each weight in a discrete, second subset of the weights, constraining the second subset to move upward together with the first weight selector, and a second weight selector is movably mounted on the member for linear movement over an upwardly open sidewall of each said weight in the second subset of the weights, leaving the second weight selector free to move upward relative to the second subset, and beneath at least a portion of each said weight in the first subset of the weights, constraining the first subset to move upward together with the second weight selector.
