Actually the rule of thumb is that more weight with fewer reps builds size while lower weights and more reps builds strength.

But you're correct. If building muscle is the main goal weight lifting is the best exercise. I don't disagree with anything that anyone else has said. Walking, bike riding, swimming and everything is great for aerobics as well as muscle strengthening, but weight lifting will develop bigger and stronger muscles faster and better than anything else.
