I wanted to post this at the beginner section initially but I honestly believe powerlifters can answer this question much much better than anyone in this forum. I used to powerlift before, so I think I know I can trust powerlifting. lol
My bench went up from 175 to 275 in a span of 4 or 5 months when I was a teen. I understand this may have been due to my freaky-youthy test levels but there were football players who couldn't put ten pounds in their bench no matter what they did. Granted, by "no matter what they did" I meant "all-things-not-powerlifting-related". When they did do something like powerlifting, however, they would do them with a moronic approach. You'd have 130-pound guys attempting to squat 275 pounds when their max quarter squat is only 250. They would do that every other day.
There's like this adage of "everything works for a newbie" but why was it that only I made real progress compared to my high school buddies? It's not like they were lazy. Ignorant, yes. Lazy? Far from it. They did 50 sets of curls a week.
