1. An exercise dumbbell, comprising:
- a lifting member having a handle, a first weight supporting section disposed at a first end of the handle, and a second weight supporting section disposed at an opposite, second end of the handle;
first weights sized and configured to be supported by the first weight supporting section;
second weights sized and configured to be supported by the second weight supporting section;
a first weight selector rotatably mounted on the lifting member for selective movement along an arcuate path that partially circumnavigates the first weights, from a first position, free from beneath all of the first weights, to a second position, beneath a peripheral sidewall of only one of the first weights, to a third position, beneath respective peripheral sidewalls of at least two said first weights; and
a second weight selector rotatably mounted on the lifting member for selective movement along an arcuate path that partially circumnavigates the second weights, from a first position, free from beneath all of the second weights, to a second position, beneath a peripheral sidewall of only one of the said second weights, to a third position, beneath respective peripheral sidewalls of at least two said second weights.

Abstract
An exercise dumbbell includes a handle member and weight plates maintained in spaced relationship at opposite ends thereof. Weight selectors are rotatable into and out of engagement with different combinations of the weight plates to secure a desired amount of mass to the handle. The weight selectors selectively underlie peripheral portions the weights to secure the weights to the handle member. Different arrangements may be used to bias the weight selectors toward desired orientations relative to the weight plates, and/or to lock the weight selectors in desired orientations relative to the weight plates.

7. An exercise dumbbell, comprising:
-
a set of first weights, wherein each of the first weights has a discrete profile when viewed from an end of the dumbbell; a set of second weights, wherein each of the second weights has a discrete profile when viewed from an end of the dumbbell; a lifting member having a handle, a first weight supporting section disposed at a first end of the handle and configured to receive the first weights, a second weight supporting section disposed at an opposite, second end of the handle and configured to receive the second weights; at least one weight selector rotatably mounted on the lifting member for rotation about a rotational axis, wherein the at least one weight selector includes (a) first segment that moves through an arcuate path about a portion of each said profile associated with the first weights, (b) a second segment that moves through an arcuate path about a portion of each said profile associated with the second weights, and only a portion of each said arcuate path underlies respective said weights, and (c) a third segment, wherein the third segment and the first segment span respective, opposites sides of the first weights. - View Dependent Claims (16)

9. An adjustable weight exercise device, comprising:
-
a lifting member including at least one weight supporting section; at least one selector rod rotatably mounted on the lifting member for rotation about a rotational axis, wherein the at least one selector rod includes at least one rod segment that extends parallel to the rotational axis at a radial distance from the rotational axis; and at least two weights configured to occupy respective positions within the at least one weight supporting section, including space disposed directly between the rotational axis and the at least one rod segment, wherein each of the weights has a discrete peripheral portion that accommodates arcuate travel of the at least one selector rod from a first position, free from beneath all of the weights, to a second position, underlying only one of the weights, to a third position, underlying at least two of the weights. - View Dependent Claims (10, 18)
