The Internet is richer for a new bizarre trend - the Belly Button Challenge or a challenge with a navel that reveals whether you need to go on a diet. All you have to do is wrap your arms around your back and try to touch your navel. If you can't do it, it's time to cut calories or start exercising, but if you can touch the navel "around the ass in the varzhet", then your body is perfect. But like many things on the Internet, this method is also controversial, because many slim bodies have not succeeded, on the other hand, some or some with stronger physiques were up to the challenge.
