I have a confession: I don't mind exercise-related pain. In fact, I welcome it. Now before you conclude that I'm a masochist, let me explain: The type of pain I'm talking about is soreness that comes after exercise and may last for a few days before going away. Known as delayed onset muscle soreness, or DOMS for short, it's a sign that your workout is making you stronger. I consider it "good" pain. That's in contrast to "bad" pain, which typically happens during exercise and gets worse afterward. It's a sign that you have an injury.
