1st week I was still in the hospital. I walked several times a day and started using the stairs in the hospital.
2nd week I was at my daughters. I walked several times a day in the hall way of her appartment and went up and down a flight of stairs each time. I also went downtown every second or third day for my INR and took the bus home.
3rd week I was still at her appartment for the first part of it. I did the same as the second week.
At 3 1/2 weeks was back home and working part days. This included walking at work.
4 weeks I was walking around the block and increasing as I felt comortable.
At 8 weeks, I started to fell a bit off, so I have slowed down the excersise regime and walk only for my daily get around stuff, like work, coffee and home chores.
The key, is to not get tired or weary and only go as far as your body tells you it is OK to go.
