Clara, Layla writes the truth. Just look at your own schedule/recovery. I'm just trying to let it all fall out. Not challenging myself per se, but not being idle, just doing the best I can and a little more.
Re your muscularity; I think I probably developed a bit of atrophy from being so inactive (I mean not completely, I was still moving around, but nearly nothing like before my real pain started to hit) over a good six months before surgery. A colleague of mine, a former LSU football player, said you need to be in very good physical shape BEFORE surgery; okay, I have trouble just getting around, like I can really work out, and before surgery! Gotta say, I can't say my possible atrophy (from inactivity) aided in my surgery and recovery! I think part of my "luck" is skeletally where I have wide hips compared to my ribcage and maybe aided in my anterior approach; my OS and I did kind of have that discussion.
Each day will bring a new stage of recovery, mostly good...could be worse than the day before if you tax yourself. Baby steps!
