You clip it around the skinny part of your waist and then twist it around so it doesn't hurt because (in theory) your waist is smaller than your ribs. This is great for push ups because you can kind of bend over so you can make sure your boobs are pushed up as far as they can for maximum cleavage. It's the only way I can get a bra on tbh. It takes too long the other way.
my mind is blown tbh
