1. A method of adjusting weight resistance to exercise, comprising the steps of:
- providing a weight lifting member having weight supports and defining a longitudinal axis;
providing weights sized and configured to be supported by the weight supports;
providing a weight selector assembly having a rod that is sized and configured for insertion into at least some of the weights, and a block that is rotatably mounted on the rod;
selectively rotating the block between a first orientation relative to the rod and a second orientation relative to the rod; and
moving the selector assembly into a latched position relative to the lifting member to connect a first selection of the weights to the lifting member when the block occupies the first orientation relative to the rod, and to alternatively connect a discrete, second selection of the weights to the lifting member when the block occupies the second orientation relative to the rod.

Abstract
An exercise dumbbell includes a handle assembly and weight plates maintained in spaced relationship relative thereto. At each end of the dumbbell, a weight selector is maneuverable into and out of engagement with desired weight plates to secure same relative to the handle assembly. The weight selector includes both a first selector rod segment that is configured to selectively engage at least a first one of the weight plates, and a second selector rod segment that is configured to selectively engage at least a second, discrete one of the weight plates.

7. An exercise dumbbell, comprising:
-
a handle assembly having a handle that defines a longitudinal axis, and weight supports secured to opposite ends of the handle; first weights and second weights sized and configured to be supported by the weight supports at respective ends of the handle; and a first weight selector assembly and a second weight selector assembly, wherein each said weight selector assembly includes a rod that is movably mounted on the handle assembly, and a block that is movably mounted on the rod, and each said weight selector assembly is selectively maneuverable into engagement with different combinations of respective said weights, including a first combination wherein the block occupies a first position relative to the rod, and a discrete, second combination wherein the block occupies a discrete, second position relative to the rod. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. An adjustable weight exercise system, comprising:
-
a handle assembly having a handle that defines a longitudinal axis, and weight supports secured to opposite ends of the handle; first weights and second weights sized and configured to be supported by the weight supports at respective ends of the handle; a base sized and configured to support the first weights and the second weights at a fixed distance apart from one another; a first selector rod and a second selector rod, wherein each said selector rod is movably mounted on the handle assembly for selective engagement of different combinations of respective said weights; and a first selector block and a second selector block, wherein each said selector block is movably mounted on a respective selector rod for engagement of additional combinations of respective said weights when the selector block is selectively repositioned relative to the rod. - View Dependent Claims (17, 18, 19, 20)

21. An exercise dumbbell, comprising:
-
a handle that defines a longitudinal axis; weight supports mounted on opposite ends of the handle; weights sized and configured to be supported in respective, axially spaced positions defined by the weight supports; and a weight selector on the handle assembly, wherein the weight selector includes a first selector rod segment configured to engage a first subset of the weights upon insertion into a first passage defined by at least one of the weight supports, and a second selector rod segment configured to simultaneously engage a second subset of the weights upon insertion into a second passage defined by at least one of the weight supports, wherein the second selector rod segment is linked to the first selector rod segment, and the first passage is disposed at a first distance from the axis, and the second passage is disposed at a second, relatively smaller distance from the axis. - View Dependent Claims (22, 23, 24)

25. An adjustable weight exercise system, comprising:
-
a lifting member having spaced apart weight supports; weights sized and configured to be supported by the weight supports; a base sized and configured to support the weights; and a weight selecting means for selectively connecting different combinations of the weights to the lifting member, wherein the weight selecting means includes a first selector rod segment and a second selector rod segment that are maneuverable into different arrangements relative to the lifting member, including a first arrangement wherein the first selector rod segment engages a first one of the weights, and the second selector rod segment engages a second one of the weights, and a second arrangement, wherein the first selector rod segment engages the first one of the weights, and the second selector rod segment is disengaged from the second one of the weights, and a third position, wherein the first selector rod segment is disengaged from the first one of the weights, and the second selector rod segment engages the second one of the weights, and in each said arrangement, a common distance is defined between the first selector rod segment and the second selector rod segment.
