Keep in mind the weight gain comes from food, not the weights.
That's true in a sense, that is, you need calories to gain weight, but if you're training to add muscle mass, the heavy lifting (in combination with good eating) increases the muscle size, hence more weight.
All the training in the world will not cause you to gain mass unless you are taking in a caloric surplus - assuming you don't have a bunch of extra fat to provide energy as you lose it. Even then it's very hard to gain muscle and lose fat a the same time.
