An exercise dumbbell includes a handle member and weights positioned at opposite ends of the handle member. An additional weight forms a box about the handle member and the end weights. At least one weight selector is movably mounted on the handle member to selectively engage the end weights. At least one connector is movably mounted on the box weight to selectively engage the handle member. A circuit includes at least one sensor that generates a signal that represents how much force is required to lift the handle member and any weights secured thereto, and a display that displays the force. At least one latch prevents movement of the selector and/or the connector when the handle member is removed from a support base for the weights and the handle member.

1. An exercise dumbbell, comprising: a plurality of weights;a handle assembly including a weight selector movable to at least two positions to engage none, some, or all of the plurality of weights, whereby engagement of the weight selector with any specific weight of the plurality of weights joins that specific weight to the handle assembly; anda sensor that senses a current position of the weight selector. 2. The exercise dumbbell of claim 1, further comprising a processor that receives a signal from the sensor indicating the sensed current position of the weight selector, the processor utilizing the signal to calculate a weight amount of the dumbbell. 3. The exercise dumbbell of claim 1, wherein: the plurality of weights comprises a first set of weights and a second set of weights; andthe weight selector comprises:a first weight selector movable into engagement with individual weights of the first set of weights; anda second weight selector movable into engagement with individual weights of the second set of weights. 4. The exercise dumbbell of claim 3, wherein changes in position of the first weight selector or the second weight selector causes the sensor to signal a change in a weight amount of the dumbbell. 5. The exercise dumbbell of claim 3, wherein the first weight selector and the second weight selector move relative to a portion of the handle assembly. 6. The exercise dumbbell of claim 1, further comprising a display operatively connected to the handle assembly. 7. The exercise dumbbell of claim 6, wherein the display presents either or both: a first visible signal upon the handle assembly being engaged with a base to indicate that the weight selector is adjustable; anda second visible signal upon the handle assembly being disengaged from the base to indicate that the weight selector is not adjustable. 8. The exercise dumbbell of claim 1, further comprising: a secondary weight selectively connected adjacent the plurality of weights; anda connector that is movable into and out of engagement with the handle assembly to selectively connect the secondary weight to the handle assembly. 9. The exercise dumbbell of claim 8, wherein: the handle assembly comprises a handle including opposing first and second ends; andthe connector is movable into and out of engagement with at least one of the first and second ends of the handle assembly. 10. The exercise dumbbell of claim 1, further comprising: a base sized and configured to support the plurality of weights; anda peg that aligns with a portion of the handle assembly;wherein:as the plurality of weights is placed onto the base, the portion of the handle assembly engages the peg and allows movement of the weight selector; andas the handle assembly is removed from the base, the portion of the handle assembly disengages the peg and limits movement of the weight selector. 11. The exercise dumbbell of claim 1, wherein each of the plurality of weights includes a plate, a slot defined within a portion of the plate, and an engagement feature positioned adjacent an end of the slot, the engagement feature operable to selectively engage the weight selector to secure the plate to the handle assembly. 12. The exercise dumbbell of claim 1, wherein the weight selector is moved into and out of engagement with individual weights of the plurality of weights by moving the weight selector relative to a portion of the handle assembly. 13. The exercise dumbbell of claim 12, wherein: the handle assembly includes a shaft; andthe weight selector moves relative to the shaft. 14. The exercise dumbbell of claim 1, further comprising an electronic display operatively associated with the sensor to display a weight amount of the dumbbell based on information from the sensor regarding the position of the weight selector. 15. The exercise dumbbell of claim 14, wherein the electronic display is disposed on the handle assembly. 16. The exercise dumbbell of claim 1, further comprising a base that supports the plurality of weights. 17. The exercise dumbbell of claim 16, further comprising an electronic display that presents a first visible signal upon the handle assembly being engaged with the base to indicate that the weight selector is adjustable, and a second visible signal upon the handle assembly being disengaged from the base to indicate that the weight selector is not adjustable. 18. The exercise dumbbell of claim 16, wherein: the handle assembly includes a shaft; andthe weight selector moves relative to the shaft. 19. The exercise dumbbell of claim 16, further comprising: a discrete weight selectively engaged with the handle assembly by a connector member; anda connector sensor mounted on the handle assembly for detecting the state of engagement of the discrete weight with the handle assembly;wherein the connector sensor generates a signal that adds the weight of the discrete weight to a weight amount of the dumbbell when the discrete weight is engaged with the handle assembly. 20. The exercise dumbbell of claim 19, wherein: the handle assembly includes a controller;the sensor is connected to the controller;the connector sensor is connected to the controller;the controller receives information from the sensor and the connector sensor to calculate an aggregate weight amount of the dumbbell; andthe aggregate weight amount of the dumbbell is shown on the electronic display.
