Mix up your abs routine with this circuit that takes top moves from three belly-toning practices—Pilates, yoga, and ballet—to strengthen your midsection and erase any muffin top. Try it on its own for a complete workout or tag it to the end of a cardio session for an extra core challenge (which is never a bad thing!).
