Practical experience works. You can be a pretentious redditor and say its slower and it ahs this or that problem, but it works. People experimented, listened to anecdotes fomr other body builders, and managed to build a system out of it, that produced demi-Gods like Arnold, Stever Reeves, etc. Modern day science muscle nerds have produced shit. Layne Norton is less impressive than a random grug-brained background bodybuilder in Pumping Iron, who probably did some sort of bro-split, even taking roids in to account. <|endoftext|>
