Stop Progress on Purpose? (SL 5x5)

lavendy17

I have a question that is probably very far in the future for me but I still wonder because I know it will eventually happen.
I plan to start Strong Lifts 5x5 very soon, probably when I get back from my honeymoon in mid June.
So let's say I do this program for a while, adding weights, looking better and then I reach a point where I am happy with my body.
Do I then stop adding weights? Do I just keep doing the same thing with the same weights if all I want is to maintain the body I have?

Thanks!
