My buddy that weighs 375lbs needs to get off the couch and starting walking/running. My relative that has blood-pressure going through the roof should have gone to the gym his whole life. My stubborn belly fat would go away if I would just eat healthier.
But I have a buddy who goes to the gym and eats healthily and is shredded. He "doesn't" need to eat healthily or go to the gym or do more cardio. But he does.
Because he does, he really doesn't have to. If he stops all those things, he'll have to do them.
His good habits have put him in a position to not desperately need to form them. If he breaks those good habits, he'll need them again.
Focus on forming good habits to put yourself in a position to NOT need those habits, but still, keep doing the good habits.
