24 hours since BBL/ fat grafting from waist area & transferred to the buttocks. Should I be standing or walking a "certain" way?

Had a Brazilian butt lift--fat was grafted from my abdomen, sides, lower back, love handles. ---I was already up and walking around for a few hours after I got home from surgery. Is there certain standing position I should be standing in or way to walk that will yield the best results, so that I don't disrupt the healing process? My abs are so sore, and so is my butt. (Ex of answers I'm looking for: hunch over a little, or have more weight on my heels vs ball of foot and toes, knees bent or straight, etc)
