Scientists at Northumbria University have discovered the key to making your moves a hit with the opposite sex: use the top half of the body and avoid waving your arms around "like a lunatic".

Evolutionary biologists asked male and female dancers to perform different moves in front of a panel of volunteers to identify the most appealing routines.

For a man, the key is to make larger movements of the head, neck and torso. For women, the bottom half is more important.

Wild arm movements were deemed unattractive for both sexes.
