Traditional fitness equipment is gravity-weighted, that is, the free weight is changed by the addition or removal of iron weight stacks. For example, a weight stack of the fitness equipment used in Europe and America mostly weighs 10 pounds usually. Five-pound stacks are not so commonly seen. The lightest ones weigh 2.5 pounds. That's to say, the minimum free weight added or removed in the training is 2.5 pounds.
