That is a better question.
It depends. We would have to see your technique, your routine, your intensity.. that sort of thing. I always feel sore when I leave the gym. However, some muscle groups feel more sore for me than others. Sometimes I will feel more sore than usual. My chest, for example, never gets a deep aching sore like my quads do from squatting. I have sufficient growth in my chest, though.
Basically, if you worked out the day before, you need to rest at least 48-72 hours depending on what muscle group you worked. Abs can be done every other day, but deadlifts put a lot of strain on your lower back, and should probably only be done once a week. I only do them every other back workout, and I have a solid pull.
I will have an off day from time to time, and lets say I come home from chest/tris, and my tris don't hurt. Does that mean I should go the next day and work my tris? Fuck no. They're still healing, I've ripped my muscle, regardless of if it hurts or not.
Take what you will from the above, it's a little all over the place, but is my answer to your question.
