calories cant really be burned during resistance training like ab workouts. resistance builds muscle, which in turn raises metabolism to burn calories. when toning muscle, its for the long run while cardio burns a lot in a shorter time. its probably burning less than 70 (rough estimate) if its for about 30 minutes
