Take a trekking pole or maybe two...can help with balance and getting up and down.  Hug or hold a tree.  Use a tree or log or rock as a back rest...generally what I look for.  

Some people I know, male and female, find it best/easiest  to remove all lower clothing except footwear although you need to pick your location more carefully.

Also scout for a location and dig the hole when you get to camp so things are ready when and if you need them.   It also spreads out the "work" reducing the stress.
