Ummm a lot of things. Lol
I'm super short torsoed so my belly take up my while abdomen.
Going potty. I have to spread my legs wide to sit down.
Doing laundry. My belly gets in the way of getting to the machines.
Getting of the couch.
Really everything. I'm 5ft 1in and have no torso so I get uncomfortable very quickly.
I'm mobile.... sorry for the typos!
