IMO isolation movements are great for 260lb+ bodybuilders who want to finish off a physique, but if you are 220 or less, like most of us here, you probably just want more muscle mass, which is made with heavy mass building exercises, not with high rep 12kg bent over delt raises.

Let's face it, once you can do greater than 140kgx8 extremely strict barbell rows you will NOT have under-developed rear delts.
