The Weight Lifter is a man from LEGO City who's dedicated his entire life to becoming the strongest man possible. He will seek to pick up essentially anything around him that isn't fixed to the ground and lift it over his head, regardless of what it is. Even if it's people, animals, cars or even small buildings like sheds. Really the only thing the Weight Lifter pays attention to is how heavy something is, and if it's heavier than the last thing he picked up.
