The overload principle states that in order to improve muscle strength, a greater than normal stress or load must be placed on the muscle. In this case, using resistance that requires strong contraction of the muscle at 80% of maximum voluntary contraction (MVC) represents an overload, as it requires the muscle to work harder than it normally would.
