FROM a Kung-Fu professional to a mini incredible hulk, these are the babies you wouldn't want to mess with. Fit enough to show you up in exercise class, these three tots show off their muscles and strength in these bizarre set of photographs.

Eric explained 'Some of the positions were easy to capture, but others became quite a problem. 'We knew that we would have to get a baby to open his mouth to look like he was screaming for the karate chop photo, but we could not get anything that looked good.
