I'm not all that mobile. As I mentioned in an earlier post, I can only walk with a walker. However, I do my physical therapy exercises most every day. I start in my bedroom and do 20 leg lifts. (I lay on the bed.) Then I move out to the deck in good weather. In bad weather, I use the kitchen counter. The deck is easier to hang on to, I get to look at some scenery and get a little vitamin D, so I prefer the deck.
I start with 20 marching steps. Then I do side leg lifts. Started with 10, worked up to 20 each leg. Then lift the leg straight out to the back 20 times each leg. Then do 20 shallow squats. Then do 20 stand up on toes and stand back on heels. I've never done these well, but I keep doing them. This is followed by 20 back kicks, like you're trying to kick your butt. I then do 20 twists to each side at the waist. I end with 20 marching steps again. After a few months, I was a little more used to it and now do a second run through of each. Again, these were given to me by the physical therapist. They're not terribly difficult, but do take some getting used to.
