I'm not trying to get any particular number of steps in while I'm recovering from knee surgery, but I am trying to move about enough so that my knee doesn't lose mobility. I'm keeping a lot of the weight off of the right knee but putting it through the proper motions for walking.
I usually put my fitbit in my right pocket. I looked, for curiosity's sake, to see if it was recording anything. Turns out it records the steps if I have it in my left pocket but not so much in my right pocket. Interesting.
