Lateral head of tricep - how to really target it?

[SaintGJR7]

Hi everyone - as per the title.

I need to bring that part of the tricep up - i think i have a bigger long head than lateral head and would like some more size on the lateral head.

I know people will no doubt say you cant isolate different parts of the tricep - however there are certain exercises which place more emphasis on the lateral head as opposed to the other 2 heads.

Which work the lateral head in your opinion?

When I do decline DB extensions I really feel it in that area more than any other exercise.
