Thanks everyone for the well wishes and words of encouragement.
I wandered around the house while my wife was at work (not comfortable attempting the steps leading to the great outdoors), then we walked up and down the block a few times before dinner. I stood at the counter and helped with food prep, and between the walk and standing, I was a little sore for the rest of the night. Somewhat amazed at the progress (physically) that's been made in 4 days.
In the truest sense of TMI (too much information), I had my first BM today.
