Welsh steel forged in Poland
James Hook insists two punishing training camps at the former Polish Olympic training village of Spala boosted Wales' World Cup campaign.
"We have built a club environment rather than an international one," said Hook, who will play club rugby in France with Perpignan post-World Cup.
"It is difficult when you go from your region to an international, but from the Poland trips right the way through we have been together and built the club environment, which has worked.
"Poland built a base for us. There were some tough days, but when you look back it was definitely all worth it.
"Training four or five times a day was not pleasant at the time, but when you look back it has paid dividends.
"I found it tough physically. It was tiring and taxing. We had not done it before, but everyone came through it for the better.
"If we continue what we have been doing in the tournament so far and cut them out, I am sure we can get the result we want."
