You BELEIVE this? But your not sure if it is correct?
Don't base your opinions so heavily just on the articles you read here (or anywhere else for that matter).
You should only beleive the things which you have experienced yourself to work and seen other successful people use. If you really beleive in something in that way then it doesnt particularly matter if other people think it is "correct".
Is this strategy woking for you? if so then stick with it.
I've always kinda followed tom platt's advice of heavy weight AND high reps. i've seen really good shoulder growth using john meadow's stuff like heavy dumbbell lateral swings for 30+ reps. its the same thing with squats. doing breathing squats (heavy weight for 20+ reps) kicks your ass.
but in general, find something that works for you and stick with it until it doesnt work anymore. then switch it up.
It comes down to what is actually working for you, not what someone else endorses. Platz stood out because of his high volume for legs....which should tell you something since many others didn't take the same approach.
It worked for him....almost to his own detriment.
My shoulders are what most comment on and I do not use high reps. I do go fairly heavy....doing more weight than most on side laterals...and it shows.
I don't see anyone who can side raise more than 60lbs with 'decent' form who has small delts.
Get stronger and train them often. That is what will make them pop out.
