You should find that your abs hate you, your obliques want to cry, and your lower back is screaming in agony; in a good way, of course.
Like always, it's about the quality, especially since in the beginning, balance is going to be half the battle. I suggest people try out three sets with five circles going each direction, three times a week.
Sit-ups may be popular, but so were acid bell-bottoms and parachute pants. Luckily we've gotten smarter when it comes to fashion -- let's do the same when it comes to working our abs. Ditch the sit-ups and start training smarter.
