Your muscles will grow only when they are subjected to an overload. They will not respond to anything less. Muscles will grow bigger and stronger only if you force them to. Making your muscles contract against a level of resistance they are not used to will eventually cause them to adapt and grow stronger. But once they have adapted sufficiently , this progress will stop. When this happens , the only way to make your muscles continue to grow is by further increasing the amount of overload to which you subject them. And the primary way of doing this is to add weight to your exercises.
Of course , this increase in resistance has to be done gradually. Using too much weight too soon usually makes it impossible for you to perform your sets using the proper technique and can also increase the risk of injury.
