I wear them all the time especially if I don't have time to get to the gym and then at least I know I'm doing something for my body'.
She added 'they make your legs feel toned and bum feel pert, they are like magic shoes! I've been wearing them to tone up for the summer and have really seen a difference, which is why I didn't mind getting my hotpants on for the video'.
