Abstract
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.
