Having done some research on this recently, the position seems to officially be called "bridge" in gymnastics. However, I think "crab" is what most people (non-gymnasts) would recognise. That's definitely what it was always called when I was at school. Lots of girls used to do them in the playground (I could never manage it...). In fact, this meaning of "pont" is in the WR dictionary: http://www.wordreference.com/fren/pont However, the question was how to translate "faire le pont", which I think would be "do a bridge (pose)/do a crab"?
