You must clearly understand the difference between basic training and special physical preparation. [SPP] is different for everybody; one beats up on a tire with a sledgehammer, another does figure eights with a kettlebell, and someone incline presses. Basic training is roughly the same in all sports and aims to increase general strength and muscle mass. Powerlifting was born as a competition in exercises everybody does.
