I don't have a pullup bar and don't intend to get one at my current apartment

What the apartment hand is this: http://www.bodybuilding.com/exercises/exerciseImages/sequences/177/Male/l/177_2.jpg Except it has two separate unconnected handles instead of a close grip handle

Aside from using less weight, what are some things you can do in terms of positioning/the way you pull to use less abs?

I don't really intend to work abs/core and don't want to make them bigger for aesthetic reasons - I never get lean enough to show them anyway and just want a smaller midsection overall and larger lats for a more v look

Currently when I do this exercise, I almost always end up using some abs/core.

Maybe does facing the other way help? Pulling the shoulders back?

If it helps at all, I usually use unconnected handles and pull downward in a neutral grip for both hands- I'm going to use this position and won't be doing underhand chinup or wide grip for no other reason than I just like how a neutral position feels.
