As humans we are not perfect and we will have imperfections. One of which are physical imbalances; left and right, front and back, top and bottom. Once we are comfortable with the form of a bilateral exercise, such as the barbell bench press, we can transfer it to a unilateral form – the dumbbell chest press. If we have an imbalance one arm will generally be weaker than the other. Our goal now is to balance both arms with independent resistance.
