On second thought, i have been wondering whether working out can be offered as legitimate penance.
Everyone who has done real exercise knows it takes a lot of discipline, determination and will power, and even someone like myself, who has always been "athletic" and active, many times i feel like not exercising at all. I feel i would much rather not exercise and do something else because it takes time and discipline.
Exercising involves some pain almost everytime, and in some cases a lot of pain and suffering.
Just go ahead and try to do Tabata sprints, or just any type of interval training; you feel like you're gonna faint and it's really hard.
Lazy people can dismiss exercising all they want; they don't have what it takes and i would like to see them try it out. They would probably die.
It's much easier to go and comfortably read a book on a couch or relax or to go plant your butt on a chair and be in the computer than it is to go out and do some intense cardio, or lift some heavy weights.
Lately i have been feeling like i don't want to exercise, because it really is a chore, even though i feel a little sense of accomplishment later.
Just imagine a father of a family who can't even lift heavy water tanks or grocery bags, or can't even lift his wife and children, or move heavy things around, or change a tire, or move furniture around etc.
What about the crusaders and the knights? Were they all weaklings? What about the Vatican Guards?
