Exercise weight bars are disclosed that provide an easy and efficient way for a user to quickly remove, add, and secure weight plates to the exercise weight bars. The exercise weight bars provide weight locks that may remain attached to the exercise weight bar during the interchange of weight plates. The exercise weight bars can accept one or more weight plates on the ends thereof. The weight locks includes extension members that engage the weight plates when the weight locks are rotated to a locked position, thereby securing the weight plates to the exercise weight bar. When the weight locks are rotated to an unlocked position, the extension members are retracted to disengage the weight plates, thereby allowing the weight plates to be removed from the exercise weight bar.

The exercise weight bar recited in claim 1, wherein the first weight plate mount has a generally triangular configuration. 3. The exercise weight bar recited in claim 1, wherein the one or more handle extensions disengage a weight plate on the weight plate mount when the one or more handle extensions are rotated to the unlocked position, thereby enabling the weight plate to be selectively removed from the weight plate mount. 4. The exercise weight bar recited in claim 1, wherein each of the first and second weight plate mounts comprises a hard stop that prevents the weight plates from sliding onto the handle. 5. The exercise weight bar recited in claim 1, wherein each of the first and second weight plate mounts comprises a housing. 6. The exercise weight bar recited in claim 5, wherein the at least one slot is formed in the housing. 7. The exercise weight bar recited in claim 6, wherein the rotatable weight lock is at least partially positioned within the housing. 8. The exercise weight bar recited in claim 7, wherein rotation of the rotatable weight lock between the unlocked and locked positions enables the at least one extension member to extend out of the housing through the at least one slot or be refracted within the housing through the at least one slot. 9. An exercise weight bar configured to have weight plates quickly and efficiently secured thereto, the exercise weight bar comprising: a handle having a first end and a second end;a housing linked to the first end of the handle, the housing having a first end, a second end positioned further away from the handle than the first end, and a plurality of slots positioned between the first and second ends of the housing, wherein the housing is adapted to have one or more weight plates positioned thereon;a hard stop disposed at the first end of the housing to prevent the weight plates from moving onto the handle; anda rotatable weight lock positioned at least partially within the housing, the rotatable weight lock being rotatable about an axis that is generally parallel to a longitudinal axis of the exercise weight bar between a locked position and an unlocked position to selectively engage or disengage weight plates positioned on the housing, the rotatable weight lock comprising: a plurality of extension members that extend through the plurality of slots of the housing to selectively engage the weight plates when the rotatable weight lock is rotated to the locked position, and wherein the plurality of extension members is retracted through the plurality of slots into the housing so as to disengage the weight plates when the rotatable weight lock is rotated to the unlocked position; anda weight lock handle disposed at the second end of the housing, the weight lock handle facilitating rotation of the rotatable weight lock between the unlocked and locked positions, the weight lock handle comprising one or more handle extensions, wherein the one or more handle extensions extend beyond a cross-sectional profile of the housing to engage and secure a weight plate on the housing when the rotatable weight lock is in the locked position, and wherein the one or more handle extensions do not extend beyond the cross-sectional profile of the housing when the rotatable weight lock is in the unlocked position, thereby enabling one or more weight plates to be selectively positioned on or removed from the housing. 10. The exercise weight bar recited in claim 9, further comprising a housing, a hard stop, and a weight lock disposed at the second end of the handle. 11. The exercise weight bar recited in claim 9, wherein the housing has a cross-sectional shape that generally corresponds to the cross-sectional shape of an aperture in a weight plate that is received on the housing. 12. The exercise weight bar recited in claim 9, wherein the plurality of slots includes two or more slots that are longitudinally spaced apart between the first and second ends of the housing. 13. The exercise weight bar recited in claim 12, wherein the plurality of extension members includes two or more longitudinally spaced apart extension members, wherein the two or more longitudinally spaced apart extension members correspond to the two or more slots such that the two or more longitudinally spaced apart extension members extend out of the two or more slots when the rotatable weight lock is rotated to the locked position. 14. The exercise weight bar recited in claim 9, wherein the plurality of slots extend generally parallel to the circumference of the bar. 15. The exercise weight bar recited in claim 9, wherein the plurality of extension members is extended and retracted through the plurality of slots of the housing by rotating the plurality of extension members generally about an axis that is generally parallel to the longitudinal axis of the exercise weight bar. 16. A weightlifting device, comprising: a handle having a first end and a second end;a plurality of weight plates that correspond to the first end and a plurality of weight plates that correspond to the second end; anda first latching mechanism associated with the first end and a second latching mechanism associated with the second end, wherein each of the first and second latching mechanisms comprises: a wall at least partially defining a hollow interior portion, the wall having a cross-sectional profile and being configured to receive one or more of the plurality of weight plates;a plurality of slots formed within the wall;a rotatable locking mechanism that rotates within the hollow interior portion and about an axis that is generally parallel to a longitudinal axis of the weightlifting device, the rotatable locking mechanism having a locked position and an unlocked position, wherein a portion of the rotatable locking mechanism extends through the plurality of slots and engages one or more of the plurality of weight plates when in the locked position, wherein a portion of the rotatable locking mechanism does not extend through the plurality of slots when in the unlocked position; anda latching mechanism handle that facilitates rotation of the rotatable locking mechanism between the unlocked and locked positions, the latching mechanism handle comprising one or more handle extensions, wherein the one or more handle extensions extend beyond the cross-sectional profile of the wall to engage and secure a weight plate on the wall when the rotatable locking mechanism is in the locked position, and wherein the one or more handle extensions do not extend beyond the cross-sectional profile of the wall when the rotatable locking mechanism is in the unlocked position, thereby enabling one or more weight plates to be selectively positioned on or removed from the wall. 17.
