1. An exercise dumbbell, comprising:
- a handle member having a handle that defines a longitudinal axis, 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 occupy the first weight supporting section;
second weights sized and configured to occupy the second weight supporting section;
a weight selector movably mounted on the handle member for movement parallel to the longitudinal axis between a first position, underlying one of the first weights, and a second position, free to move upward relative to said one of the first weights; and
a knob rotatably mounted on the handle member for rotation about a knob axis that extends parallel to the longitudinal axis, wherein a contoured bearing surface on the knob bears against the weight selector to alternatively hold the weight selector in the first position and the second position as a function of orientation of the knob relative to the handle member.

Abstract
An exercise dumbbell includes a handle member and weight plates maintained in spaced relationship at opposite ends thereof. Knobs on the handle member have contoured bearing surfaces that bear against respective selector members to alternatively hold the selector members in weight engaging positions and disengaged positions.

8. An exercise device, comprising:
-
a weight lifting member; weights sized and configured to align with the weight lifting member; a weight selector movably mounted on the weight lifting member for movement between a first position, underlying one of the weights, and a second position, free to move upward relative to said one of the weights; and a knob rotatably mounted on the weight lifting member for rotation about a knob axis, wherein a contoured bearing surface on the knob bears against the weight selector to alternatively hold the weight selector in the first position and the second position as a function of orientation of the knob relative to the weight lifting member. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of adjusting resistance to exercise, comprising the steps of:
-
providing a lifting member having at least one weight holder; providing weights sized and configured to occupy the at least one weight holder; mounting a weight selector on the lifting member for movement along a path between a first position, underlying one of the weights, and a second position, free to move upward relative to said one of the weights; and mounting a knob on the handle member for rotation about an axis extending parallel to the path, and in such a manner that a contoured bearing surface on the knob bears against the weight selector in a manner that alternatively holds the weight selector in the first position and the second position as a function of orientation of the knob relative to the handle member.
