verb / noun
tug
TUG/tʌɡ/
A strong pulling action.
The woman tugs hard on the rope to move the heavy sack.

Etymology
Old English teohan combined pulling with rough handling and dragging. Tug preserves that forceful side of pulling: the emphasis is on an exertion of force, not simply moving something toward oneself.
In context
when you pull your belly button in to activate your transverse abdominis, it does tug on your diaphragm
