Why do people keep thinking in extremes lol?
I did lateral raises all the way from 105lbs to 210lbs bodyweight and repping 225lbs for the Overhead Press. Every one I know who went from small to big did this before the Internet. They didn’t wait until they got to some arbitrary size or strength level before they decided, “Hey guys. look at us! We’re jacked! Now we can do some side raises! Yay!” If that really happened, being people with common sense, they would have said, “Wait, we’re jacked as fuck! Why the fuck should we do side raises if we already have proportional delts? This doesn’t make any fucking sense! You’re fucking with us, aren’t you?”
Note: @samul Side raises 3 times a week is overkill. Once is enough. Unless the program states otherwise.
