The Strength Machine is designed to have resistance when raising the bar. In step 19 of the build instructions (from Bag 6/7), you can see that one of the resistance gears is held by a tan pin (turns easily) and one is held by a blue pin (high friction). I don't know how the resistance might compare between models after they are used for a while.
