A weight selection and adjustment system for a selectorized dumbbell, which comprises:

• (a) a selectorized dumbbell, which comprises:
• (i) a stack of nested left weight plates and a stack of nested right weight plates;
• (ii) a handle having a left end and a right end;
• and
• (iii) a movable selector having a plurality of different adjustment positions in which the selector may be disposed, wherein the selector is configured to couple selected numbers of left weight plates to the left end of the handle and selected numbers of right weight plates to the right end of the handle with the selected numbers of coupled weight plates differing depending upon the adjustment position in which the selector is disposed, thereby allowing a user to select for use a desired exercise weight to be provided by the selectorized dumbbell;
• and
• (b) means selectively actuable by the user for adjusting the exercise weight of each dumbbell without requiring the user to physically contact and move the selector himself or herself.

A weight selection and adjustment system for a dumbbell, which comprises:

• (a) a dumbbell that provides an exercise weight that is lifted by a user when the user grips and lifts a handle of the dumbbell, wherein the exercise weight provided by the dumbbell is adjustable by coupling more or fewer weight plates to each end of the handle;
• (b) an electric motor that may be selectively energized and when energized will cause a desired number of weight plates to be coupled to each end of the handle;
• and
• (c) a data entry device to allow the user to input a weight selection decision that operatively controls the energization of the motor to adjust the exercise weight of the dumbbell in accordance with the weight selection decision input into the data entry device by the user.
