What I believe Unident meant (and please, correct me if I'm mis-assuming, Deb) is that being sore should not be the goal.
What soreness means is that you have done something new, or particularly challenging. It's not a goal in and of itself. You don't want something that will hurt you; you want something that will challenge you. Soreness is a side effect, not a sign of effectiveness. :)
Just about any workout you do (even yoga) can cause soreness the next day, if you aren't familiar with it or try something more intense than usual. Your body will adapt, and it won't hurt anymore, but that doesn't mean it's not effective.
I'll admit, I like it when I'm after a good workout; however, that isn't my goal when picking up those weights.
Writer, mother, wife, and breadwinner. I love to run, but running doesn't love me, so I'm switching to my low-impact bike.
