Hula hoop

Hi I was just wondering I bought a weighted hula hoop yesterday 1.3kg and ive got bruises which i read is normal the first couple of times you do it but i was wondering how much success with weight loss have people had with this kind of exercise ?:) im on slimming world diet to but after losing 17lb im on a stand still and thought this would help to push my weight loss further. I'd love to do tricks but my hoops massive and heavyish and ive tried using a smaller lighter one but it was flimsy and i couldn't keep it spinning.
