ok so we hit the big shoulder presses heavy, 6-8 heavy reps so this makes us strong, and strong muscles are big muscles right! so with rear delts why the hell do so may people and trainers use light reps!!! (no scientific study to show that rear delts respond to higher reps that ive read) so why not hit rear delts with heavy weights to???????
this question could apply to forearms and abs to i guess
