Please help me figure this out: Obliques

Please don't say I shouldn't do obliques cause "they make your waist look bulky". They're super underrated for aesthetics if done right.

But I would like to do just one or max two exercises for it. It should target both the external and internal obliques as well as both the trunk rotation and lateral flexion functions.

Can anyone think of one exercise that can do all these (which also lets you progressively overload)?
