Fit, or Fit for the Purpose

[Highlander]

I think that the saying, `No pain, No gain` was coined in the Army, because they always said [ or made us ] work until you were at least in a tired condition saying that the most benefit gained is achieved after the body starts to become stressed,... otherwise all you were doing was exercise for recreation.

My limit these days is that when I come off the hill with the dogs, my legs are tired and I am breathing heavy, and sweaty if the weather is warm, and warm if the weathers cold

so I think I am happy with the amount of exercise I am getting,..add to that other more manageable things like sawing/chopping wood,..and that will do me

.... my work also entails a certain amount of exercise.
