1. An adjustable weight exercise device, comprising:
- a base;
a first set of weights including a first weight plate and a second weight plate maintained in alignment at a first end of the base, and a second set of weights including a first weight plate and a second weight plate maintained in alignment at an opposite, second end of the base, wherein each said first weight plate has an upwardly opening slot, and a first notch and a second notch that extend into opposing sidewalls of the slot, and each said second weight plate has an upwardly opening slot, and at least one notch that extends into a sidewall of the slot; and
a handle member having an intermediate hand grip that is sized and configured for grasping;
opposite end portions that align with respective weight plates on the base; and
first and second weight selectors that are rotatably mounted on respective end portions, wherein each of the weight selectors extends at least partially through each said weight plate in a respective set, and each of the weight selectors is rotatable from a first orientation disposed entirely outside each said notch, to a second orientation extending into only one said notch in the first weight plate, to a third orientation extending into only one said notch in the second weight plate, to a fourth orientation extending into both an opposite said notch in the first weight plate, and the one said notch in the second weight plate.

11. An adjustable weight exercise device, comprising:
-
a first weight plate configured and arranged to define an upwardly opening slot and a laterally extending notch that opens into a sidewall of the slot; a second weight plate configured and arranged to define an upwardly opening slot and a laterally extending notch that opens into a sidewall of the slot in the second weight plate; a weight lifting member configured and arranged to support the first weight plate and the second weight plate in alignment with one another, with the notch in the first weight plate extending in a first direction away from each said slot, and the notch in the second weight plate extending in an opposite, second direction away from each said slot; and a weight selecting member rotatably mounted on the weight lifting member, wherein at least one peg projects outward from the weight selecting member and at least partially through each said weight plate, and the at least one peg is configured and arranged to (a) occupy only the slot in each said weight plate when the weight selecting member occupies a first orientation relative to the weight lifting member, thereby accommodating upward movement of the weight lifting member relative to each said weight plate, and (b) occupy the notch in the first weight plate and the slot in the second weight plate when the weight selecting member occupies a second orientation relative to the weight lifting member, upon rotation in a first direction away from the first orientation, thereby accommodating upward movement of the weight lifting member and the first weight plate relative to the second weight plate, and (c) occupy the slot in the first weight plate and the notch in the second weight plate when the weight selecting member occupies a third orientation relative to the weight lifting member, upon rotation in an opposite, second direction away from the first orientation, thereby accommodating upward movement of the weight lifting member and the second weight plate relative to the first weight plate. - View Dependent Claims (12, 13, 14, 15)

16. An adjustable weight exercise device, comprising:
-
a first weight plate configured and arranged to define an upwardly opening slot and a laterally extending notch that opens into a sidewall of the slot; a second weight plate configured and arranged to define an upwardly opening slot and a laterally extending notch that opens into a sidewall of the slot, wherein the notch in the first weight plate extends laterally further than the notch in the second weight plate; a weight lifting member configured and arranged to support the first weight plate and the second weight plate in alignment with one another, with the notch in each said weight plate extending in a common direction away from each said slot; and a weight selecting member rotatably mounted on the weight lifting member, wherein at least one peg projects outward from the weight selecting member and at least partially through each said weight plate, and the at least;
one peg is configured and arranged to (a) occupy the slot in each said weight plate when the weight selecting member occupies a first orientation relative to the weight lifting member, thereby accommodating upward movement of the weight lifting member relative to each said weight plate, and (b) occupy a first portion of the notch in the first weight plate and the slot in the second weight plate when the weight selecting member occupies a second orientation relative to the weight lifting member, upon rotation of the weight selecting member in a first direction away from the first orientation, thereby accommodating upward movement of the weight lifting member and the first weight plate relative to the second weight plate, and (c) occupy the notch in the second weight plate and a second portion of the notch in the first weight plate when the weight selecting member occupies a third orientation relative to the weight lifting member, upon further rotation of the weight selecting member in the first direction, thereby accommodating upward movement of the weight lifting member together with each said weight plate. - View Dependent Claims (17, 18, 19, 20)
