I decided to walk across to the retail park today. When I got back and checked my fitbit it said that I had covered 5.4 miles for the day.
Seeing that I had only been pottering about in the house before that including a lot of time at my computer desk, I must have walked near enough five miles. Normally I would have been in pain and my lower back almost completely seized. I am happy to say that I only had sore feet (probably from wearing light trainers), a few achy muscles and a slight pain in my lower back. I could have happily continued.
Feel free to use this as a recommendation.
