I just did 20 minutes on the treadmill, and it was the best minutes I've spent in a long time. (I was given the go ahead by my physio friend)
Actually, I think that it's helped me to get back to walking normally - I've been limping, but trying to get back to walking properly, but it's quite hard. On the treadmill you don't have time to think about how you're walking, you just do it. When I got off my walking was better than when I got on. Definitely a reason to keep it up. My mood was better too :)
Have you moved your body today?
