When you get a blood test, they tell you not to exercise for 24 hours. 8 hours later, admonition completely forgotten, I walk home and do my usual routine of going down the Escarpment stairs, by hoisting my 110 kilos up on the railings, holding it there for a bit, and swinging down two or three steps, and repeating, all the way down. This does indeed constitute exercise. Rather strenuous exercise at that.
This is my arm 8 days later. And it looks a lot better now than it did 4 or 5 days ago.
When you get a blood test, and they tell you not to exercise for 24 hours - don’t!
