OH, PEAR SHAPES!!!!!

I've recently stumbled upon a great cardio workout: STEP AEROBICS! I'm desperate to continue with this workout as it's much more exciting than that dull dreaded treadmill and it curbs the chub rub. However, I read that as a pear shape, I should avoid this workout as it will only bulk me up. How true is this?

Please feel free to add me, fellow pears!:)
