Muscle Imbalances
Muscle imbalances occur when a muscle on one side of your body is bigger or stronger than its counterpart muscle located on the opposite side of your body. For example, your right bicep may be bigger than your left bicep.
The reason behind muscle imbalances is an unbalanced usage of both muscles. The bigger or stronger muscle had been overused or overtrained while the weaker, smaller, or tighter muscle hadn’t been used or trained as often. One way to correct muscle imbalances is to include unilateral exercises such as concentration curls in one’s fitness programme.
