Thanks all! I was a little low energy before posting today, but after all the encouragement, I looked online for some post tkr beginner hamstring exercises, got on the floor and did a few bridges, put my feet on a big exercise ball and pulled toward me, held onto the couch and bent my knee lifting my foot (that was harder) and then put a cherry on top by walking on my treadmill 1/4 mile for the first time. I have walked up to about 4200 steps in a day but not that much at one time. Last time I got on the treadmill I only went .15 before I stopped. It has been a long time since I was able to do that without pain, although now my calf in operated leg feels really tight. I went slow, 1.7 mph. Now I’m sitting in the chair with ice on my knee/leg, and heat on my back, and feeling great about it!
