Meet Warren Gatland's secret weapon - Wales' fitness coach Paul Stridgeon.
Gatland has employed Stridgeon to provide an extra edge to his team and the former English representative wrestler takes his job seriously with some weird and wonderful innovations designed to help the Welsh go further than they ever have in a World Cup.
Known to players as 'Bobby', Stridgeon wrestled at the 2002 Commonwealth Games and was picked by Warren Gatland to replace Adam Beard, who left his post to join the Cleveland Browns NFL franchise in June.
Ask insiders at the Welsh camp for the secrets to their success and the name 'Bobby' quickly comes up.
He has a reputation as a joker - he entered the gym wearing the Scorch the Dragon mascot suit last week and claims he can levitate above the pavement whilst holding on to a road sign.
