Overload principleOverload principle: : – The application of greater The application of greater
than normal stress to a than normal stress to a muscle resulting in an muscle resulting in an increased capacity to do work.increased capacity to do work.
– Muscle will gradually adapt Muscle will gradually adapt – Then we will increase stress Then we will increase stress
