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;

    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; and

    a separate means for selectively securing the other first weights to the handle member in response to rotation of the knob.
