Need a Core plan

i get plenty of core training from doing weighted compound lifting movement like snatches, hang cleans, deadlifts and pullups. sometimes maybe once a month i'll do planks but on the off chance i take classes where they do "core" work i'm always the only person having no difficulty doing the situps, leg raises, pilates stuff etc.

that's pretty much been my proof that i dont need to do direct core work in order to strengthen my core.
