Weights as a symbol often relate to the idea of weight that must be carried or burdens. They also relate to the idea of exercising to increase your strength and are a tool used in the process of "body building" (which in itself is a fascinating word play). As a homophone "weight" can also relate to the concept of patience as we "wait" upon the Lord. Interestingly enough weights can also be utilized for the purpose of endurance training.
