I'm 56 and I expect a PR at every bench meet I go to. I don't always get there, but it still happens occasionally. Getting older, you just have to take a day off occasionally to let some of the nagging little things heal. My normal workout routine is 4 days/wk. Am I fit???? I can't run a marathon, but I can walk as far as I want without getting winded and I can bench a house if need be.
