The training at altitude in Fiesch and in the extreme heat near Antalya prepared Wales for a run to the quarter finals in France earlier this season before they fell to Argentina. Now Thomas feels the benefit of the hard work last summer can play into the Six Nations.
“I think all of the boys who did the summer camps probably agree we all feel fit,” said Ospreys prop Thomas.
“I hope that comes into the games in the Six Nations as well. I hope it shows that we are still fit because I probably felt the best I’ve ever felt at the World Cup.
“I haven’t had that much time off since then, so I haven’t had time to lose it I suppose, so I hope I’m still just as fit.”
Thomas will be looking to add to his 26-cap tally during the 2024 Guinness Six Nations and comes into the tournament fully fit and refreshed after missing the Ospreys recent trip to South Africa.
While many are writing off Wales when it comes to their title hopes, Thomas stressed the squad will not back down from any battles over the coming weeks – starting with the challenge of the Scots.
“I can’t see a team coming up against us and thinking they’re going to have an easy day,” said Thomas.
“We don’t think much about the history of what has gone on in these games in the past. We haven’t got much to lose, and we just want to get out there and win
“There is a lot of energy in the camp at the moment. We have to empty the tank from game one in this tournament and there has to be 100 per cent effort from every one.
“Since I’ve been involved, and even watching Wales before, no-one’s had an easy day against Wales. The boys we’ve got in the squad at the minute, none of us will back down in any fight.
“We’re a country that always punches above our weight. We’re going to have to do that in this campaign as well.
“With a bit of belief, and then being able to deliver on the detail the coaches give us, should see us do alright.”
