James Hook is ready to flex his new muscles to nail down the number ten Wales shirt. after working flat out in training and adding almost four kilos in muscle.
Now he hopes that bulk can help give him the edge over rival Stephen Jones when it comes to facing the world's best in the Invesco Perpetual Autumn Series.
Hook said: "There's a lot of competition at fly-half but it's now time for me to step out of the development stage and do it for real.
"I've been working hard and got huge gains from doing weights, speed and fitness work. It's the strongest I've ever felt and I'm really happy.
"At the Ospreys we've been pulling trucks and flipping tractor tyres during pre-season which was good fun. Our new fitness coaches Alex Lawson and Mike McGurn have been great and we're being monitored all the time. The fitness work has really benefited us."
Hook has found himself bowing to the experience of British Lion Jones for the coveted number ten jersey under the tenure of Warren Gatland.
But the 23-year-old showed his versitility at full-back on Wales' summer tour against the Springboks, when Jones retained his place, and Hook says that fighting for his place in the side is perfect motivation.
"Competition between Stephen and myself is nothing new. It's been there for the last few years. But I only played 18 minutes at fly-half in South Africa and now I need to impress.
"What I do at regional level will count for Wales selection and the Ospreys have some huge games early in the season. So my aim is to send a message to Warren by producing some good performances. I really want to start against South Africa on November 8."
Wales face all three southern hemisphere giants - South Africa, Australia and New Zealand - as well as Canada this November. And 27-cap Hook believes Wales can claim a major scalp.
He added: "We've got to take confidence from the Grand Slam and the way we matched South Africa in the second Test on tour. So we know we're not a million miles away from success against them."
The winners of a filmmaking competition organised by the education charity Into Film and the WRU enjoyed a behind the scenes tour of the Millennium Stadium - and a chance to be photographed with the WRU's fire-breathing, rugby loving mascot, Scorch The Dragon, and Welsh international, Jake Ball.
The Wales Under 20 camp are in a quietly confident mood as they face Ireland in the U20 Championship, with Coaching Co-Ordinator Allan Lewis and full back Dafydd Howells targeting a top five finish in the tournament.
Wales U20 may start as favourites against Japan this evening in the U20 Championship, but Team Manager Mark Taylor is warning against complacency. He is also hoping a good win will boost morale and 'kickstart' performances.
Coach Richard Hodges is hoping Wales U20 can put a disappointing campaign behind them when they tackle Japan tomorrow as they look to finish the U20 Championship strongly to secure a good seeding for next year's tournament.
