Repetitive stress always warrants extra attention and rest breaks as the years add up. Give it a rest before you push into the danger zone and 40-60 may be a breeze. You go just as far, it just takes a little longer. It's not a race.
Yesterday was a good day....Shoveled and pushed snow for around 1.5hours, very limited back strain and the knee was just going along for the ride. Odd thing to me was the PT people and the Docs never mentioned the calf when it came to the knee. They looked at the pics and said that is a pretty good knee. Don't know why it hurts. A month or so ago, I just thought you never do calf specific so why not. Lucky....
Addition: And the more I do yoga stretching, the better the flexibility. It isn't just for the girls.
