Whats the difference???!?!?!?

Between lots of reps with smaller weight vs few reps with heavyer weight? Im starting bodybuilding and I cant find a good answer, some pro bodybuilders use massive reps while others go with a few reps with a lot of weight. Which one works best for a lean, toned, ripped body like Arnold Swartzanegger?

More reps with less weight gives you definition. If you want bulk go for more weight with less reps. More weight tears down muscle and bulks it up
